Bit of advice required for the A3 again.

See previous thread:

Basically I had oil pressure issues and noises coming from the engine, replaced cam shaft, gaskets and oil pump.

Since having the car back, I'm using a litre of oil every month so I took it back to the garage. They've inspected and found that the turbo is passing oil? I brought up the 3 month warranty that's placed on my invoices and attitudes changed, apparently they've not went near the turbo so it isn't there problem? Well....there wasn't any consumption issues before they started working on it!

They've also charged me for work twice. The first time the car was inspected they didn't find any issues with the oil pump. After I took it back, they've noted on the second invoice that there was damage to the oil pump, problems with it and that the car had oil starvation as a result...surely this would've shown up the first time round? They've not looked at it properly the first time despite stating they have.

Where do I go? Live and learn or is there something I can do about this? Typical garage in the sense that their attitudes are a bit bullish.
 
It is not surprising the turbo bearings may have been damaged when the car was being ran with low oil pressure. The turbo rarely fails on the 2L TFSI engines so can be picked up cheaply second hand the other option is to get the turbo refurbished.

Out on interest how much did it cost to replace the oil pump ?
 
Cheers Dave. Yep, understand they can be damaged due to low oil pressure but the garage hasn't given the car the inspection and testing they've stated, then let me run it. The way the chap acted on the phone before hanging up, leads me to believe he knows fine well they've messed up.

I got a second hand pump on the car because, due to the value of it now and wanting rid, I didn't want to fork out £1k + labour for a new one. It cost 700 in total I believe.

personally being a mechanic, i cannot see how from replacing the oil pump, can damage the turbo seals to make it burn oil. oil may of been slowly seeping pass the seals for a while as its very common for this to happen with straight engine turn off after running and not letting the turbo cool down with the engine running at idle for a few minutes.

Does that really apply with modern Turbo cars in this day and age?
 
It's the same as fixing someones laptop, you fix the DVD drive and give it back then the person comes back a week later saying the you broke the screen. The reality of it is you did nothing and there was an underlying problem with the screen well before you went near it. It gets very complicated and messy trying to prove either way, the above is one of the main reasons i don't fix many peoples personal computers its just too much hassle if something else goes wrong you can end up losing quite a bit of money on it.
 
Thanks for the feedback guys, I get what you're saying entirely. When it comes to engines, I'm really not clued up enough to know what affects or breaks what.

All I know is that
-They took the car in, took the engine apart for inspection, top and bottom but found no damage to the bottom end or issues with the oil pump and surroundings despite the fact that there was oil pressure problems with the car. They repaired and rebuilt the top end(source of the noise I was complaining about)
-Took the car away with oil pressure problems still present. Took the car back and paid to have it stripped again. They then say that the oil pump is knackered with other things affected on the bottom end and that the car has had oil starvation as a result.

Why wasn't this spotted the first time and could it have had an impact on the turbo? In my opinion they haven't carried out the proper checks in the first place on the bottom end and instead have just opted to repair the noise coming from the top end, despite charging me a fortune to do both. They've charged me twice for the same work which is more than evident from the invoices.

I think Matt-Page is right though. Probably not worth pursuing or worrying myself over it. I'll get the turbo replaced.
 
It seems odd that they didn't just replace the oil pump at stage one, especially given the symptom of low oil pressure and the relative cheapness of the part! And now you've paid twice for them to strip it so they can fix what they should have fixed first time.

And surely if you have bottom end damage from oil starvation, you need more than just a new turbo?

Yeah, that's why I thought I'd run it past you guys after a lot of help was given in my initial thread.

The invoices state and have charged the exact same jobs, except second time round they've actually bothered carrying out the work and found the oil pump to be knackered with previous damage. If I was that way inclined I could argue that the damage listed on the second invoice was caused by their dodgy work or negligence but I wont go down that road.
 
Did the replace the piston rings with the rebuild? I can't see them listed in your last thread.

If the oil got low enough to do all that damage I would be amazed if they are not worn. For the price of them and considering they had it all stripped down I can't understand why they wouldn't do them.

This

How did they come to the conclusion its the turbo? Id expect the intake pipes to be lined with excessive oil.

To test the theory youd want to clean a section, disconnect the PCV and try again or just replace the turbo with a big hybrid
