I have read about problems with pinking on this engine in another post on here. but is this the only problem anybody has had with this engine? I don't want this to become a debate about performance drivability or anything else just about problems and faults .

Thanks Skippy . Seems that no many people on here know of many problems with this engine so i guess my parents have just being very unlucky. just over 12 weeks ago the engine mamagment light on their 11 month old 6500 mile 1.0T SE came on . The car was taken to a main dealer the next day and is still in their yard. Nobody will tell us just what the problem is only that the engine lost compression on number 3 cylinder at low revs but the car drove fine no lo ss of power smoke ect. They then said that replacing the engine might fix the problem but they didn't know for sure?? .
Thats as far as we have got as vauxhall cannot supply a new engine but won't let us reject the car with out giving them a chance to fix it. The last time my mum spoke to vauxhall direct she was told that an engine may be available by the end of August

Hi my parents have being given a base model 1.4 meriva hire car which is a horrible car after the corsa and my mum is paranoid about scratching it as it had a ÂŁ500 excess for damage. As o.a.p.s m y parents bought the SE spec as they wanted the parking sensors o make life easier but the meriva hasn't got them.

Theres a good article by Honest John about rejecting cars. The problem is if the car was bought 11 months ago it would come under the 1984 Consumer act not the October 2015 rules.
Even then they are trying to rectify the problem and its way past the 6 months, and if its on finance theres another legal step required in that the finance company have to be involved. Rejection would be difficult to pull off just now without going to court. Is why I pay cash in preference to zero percent finance.
Still at least your parents have suggested rejection which should spur them on to fix it.

Vxownertelford, it may be worth contacting Vx UK and Motorcodes the ombudsman if it's being repaired. CAB/ Trading Standards another. Court may be costly and selling cheaper than court. I paid cash for mine and additionally I'd also missed out on the new consumer rights by a matter of months. Had I paid by finance or credit card I may have had extra recourse. Tip, just by paying as much as ÂŁ1 with a credit card on the deposit involves the card company to help out.

Thanks for the advice but it seems my parents are stuck in a hole waiting for a new engine. they have spoken to vauxhall directly but customer service seems to only exsist until you buy a car after that vx don't want to know, just say its up to the supplying dealer to sort out which sucks since its vx who are unable to supply the dealer with a new engine. We will keep pushing the dealer for a solution but not sure what route to take next, I'm just glad that this seems to be a one off because nobody should have to go through this

Yes I think all consumer laws expect you to deal with the contracted party which is the dealer.

This level of severity is quite rare these days. Since I dumped my old Viva in 1984 and started getting only new Vauxhalls I have only needed one courtesy car when a speedo cable snapped. We were loaned a new Corsa B which was not fitted with power steering in those days. Awful!. However insisting on it under the terms at that time of the Roadside Assistance it speeded up the repair from quoted 2 weeks to 1 day!

This doesn't make sense. The 1.0T is a 3 cylinder engine, if it had lost compression on one cylinder due to failed head gasket, piston rings or valve issues it would struggle to run at all and you would certainly notice a loss of power, smoke and very rough running.

Also why would the dealer be unsure if a new engine would fix the problem? If they knew the problem was in the engine then a new engine would definately fix the problem unless it was a design flaw that may exist in the replacement engine - unlikely.

This suggests it may be an electronic issue and rather than a new engine it may need new ECU, wiring harness or sensors. It is often the case that Vauxhall will supply a stripped engine, this would not include the ECU, injection system, turbo, cat etc. The dealer would re-use or transfer these parts across from the original engine which is probably why they suggested a new engine may not fix the issue?

Given the number of random electronic issues I've had with my car I would not be surprised if it was an electronic issue, very difficult to track down too.

Hope you get it sorted soon!

This exact same thing happened to my 1.0T excite. I made a previous post in January about it misfiring and one cylinder had failed or something. I had the engine management light on and traction control light on - took to vx was there for 3 months had a whole new engine fitted as that was the only option. Problem was they needed to build one from scratch so was like waiting for a new car all over again. All in all everything seems fine now but tbh it did really make me want to get rid of it and go elsewhere.

Just a quick update my parents are still trying to resolve the issue and there is a possibility of an engine in the next few weeks but no guaranty. Just a quick word of warning to anybody with this engine if you suspect that something is wrong get to a dealer asap as from what I can find out engine problems are not common but are affecting a number of cars, but vx are trying to keep it quiet, hopefully they are working on a solution or at least someway of getting replacement engines sooner.

Had a problem with my 1.0T. Excessive vibration and loss of power. Took it to get checked, first dealers told me it was fine but after I insisted they check again I'm now told it has a broken piston. Waiting for news and very worried. Anyone else with the problem please keep us updated with the outcome.

Hi, I have just joined this forum .

I have a 1.0T 115 excite and the engine problems described in this thread are worrying as they could be an engine design issue rather than just a few unfortunate cases .
Recently our Corsa has started to make a random grinding humming noise, not unlike a worn bearing sound, which is coming from the engine compartment when idling and stationary.
This noise comes and goes and does not appear to be coming from the turbo, alternator or gearbox.
The car performs perfectly on the move and I have no idea what this is.
I use 99 octane fuel which seems to suit this engine better as I have not had any pinking problems.

If this gets any worse I will be taking the car back to the dealer as at the moment it is only intermittent.

Good luck willow. after 14 weeks of waiting for a new engine my parents have now being told that the engine has had to be reordered so still no idea when it will arrive, but vx customer service have also told them that theirs is the only engine that's packed up so everybody else must be mistaken, getting Fed up with the lies and bulls**t from vauxhall wish they would just come clean about how big the problem is and what's causing it

Quick update the dealer has phoned to say that the new engine has arrived, its a short motor so needs building up with cyl. Head and ancellares from the old engine and fitting which will take a couple of days but still no word on what if anything vx have done to fix the problem so just got to hope the new engine lasts longer than the old one.

Over 2 weeks ago I tweeted VX HQ that I was experiencing pinking even with high octane 97 Ron and I've read it can cause serious engine damage.
They never replied..

A few days ago I lost some power and experienced misfiring and vibration at low revs (I downheartedly suspected a cracked piston).
While dropping mine off at the VX main dealer a few guys were pushing a Corsa into the workshop.
When I asked "what's the problem" one said it was a 1L Turbo with low compression on a cylinder.

Six hours later they confirmed mine also has low compression on a cylinder.
This is pretty upsetting as this was a very smooth and quiet engine and felt like it would have lasted a long time.
I think this could've been easily avoided with a remap or firmware update?
Now I'm paying ÂŁ259 a week to hire a dual control car while this is being sorted out.
When this is fixed I'm thinking of getting a 1.4T instead. I didn't ask for a courtesy car as it's of no use to me.

UPDATE: After 3 weeks in the dealer's workshop and emailing photo's of a cracked piston to HQ they decided it needs a new engine.
From today they are paying for a dual controlled Corsa D while waiting for a back order for these engines to come over from Germany.

Sorry to hear everyone's problems. It's as if the public are doing their testing. I sold mine when she was repaired. She had a cylinder head gasket go, timing chain cover with a hairline crack, oil pump and heat exchanger gaskets go. I've now got a Japanese model.

I think this is true of most new designs from software and phones to engines.

I gather the new GM Camaro had similar problems with it's new 2.0T. That was a small engine which replaced a big V8. It suffered pre-ignition and resulted in piston failures. The fix was a different type of spark plug, different lubricant and remap AFAIK.

The more I hear about the problems with the 1.0T the more I accept that it is a design flaw.

What concerns me is that VX doesn't appear to know what the issue is. By supplying a short engine as a replacement means the dealer will have to keep the fuel injection system, ECU etc from the car. It may well be these items causing the problem and the replacement engine will be damaged in the same way as the original.

I've not suffered this at all on my 1.4T which has done 24K miles running on various fuels including cheap supermarket upto shell vpower. I thought the 1.0T and 1.4T had very similar fuel injection, turbo and piston components so I'm curious as to what is causing this knocking noise on the 1.0T.
