I'm in the UK and I've joined to try and help my partner who has a 2009 93 1.8T petrol convertible, 17,000 miles.
She took it to have an annual oil and filter change (before actual service due) and had an air filter fitted too. All done at Kwik Fit.
After driving away, there was blue smoke. Peridically, whilst cruising the engine would "choke" like engine-braking, but a change down
and dab on the accelerator kicked it back, but with a big cloud of blue smoke. Over 120 miles, it used 1.5 litres of oil. The oil that remained was
It went back to Kwik fit. They "found no leaks or problems, couldn't identify oil burning" (it didn't at tickover!). They changed the oil, but for the same type, apparently, and washed their hands of it. The same problems carried on, and after complaining again, Kwik fit said take it to a specialist
Prior to going to Kwik Fit the car had never used any oil and it stayed pretty clean. I know because I checked it regularly.
The car went to a specialist. They changed the oil for a "GM" oil and identified that Kwik Fit had used a diesel air filter instead of a petrol air filter.
We thought this was the answer. Can fitting a diesel air filter into a petrol car cause a problem? They both look similar except that the diesel version has an additional sponge layer stuck to the paper base?
I paid for the new oil and filter replacement and drove away. After a few miles, exactly the same problem returned. Periodicaly, it seems to run
ok, goes through the gears smoothly up to 5000revs, 80mph but then it feels choked, pulls back, and, after accelerator, emits a big cloud of blue smoke.
Its back with the specialist, but he seems stuck and is talking about (expensive) failed turbo's and cracked rings. Surely this cannot be just a coincidence? The car has been fine for 2 years right up to the day it went to Kwik Fit. Can an oil/filter, plus air filter change do this kind of damage?
She's now bitterly disappointed with what was previously her pride and joy, and upset about the potential massive bill. Can anyone help?
