Hi there, please help me because im stuck.

I took my audi tt 225 into be serviced at a garage round the corner from me. It had been running a little rough but no big issues. When i went to get it back it had a real lack of power and then when it creeped up to 4000rpm all the power would rush in. They took it back and replaced the ignition coils. This time when i got it back t seemed to be better then ever, loads of power and better than ever.

The next day it seemed to go again. I had lack of power and then it would all come in at once as before. i thought maybe a dodgey coil so took it back and this is where the problem is. They cant find out what was is wrong, they have changed the plugs, the ignition coils again, the fuel filter, the air filter and no joy. They said its mis-firing but they cant see why?


Does anyone know what it could be. Could it be a turbo problem and what could be causing it??
Why does the power hold back and then come all in at once?

 

do you have a boost gauge installed? you should... also, any codes?

 

Could be a faulty MAF??

 

no i dont have a boost guage, all is as factory fitted. Dont have any codes, sorry

 

what is the MAF?

 

Wastegate?

 

Mass Air Flow, right after your airbox/intake. You could try taking it out and cleaning. or take it out and run it and see if it does the same thing. you will throw a check engine light if you drive it with it off though. Real easy to clean, just get some MAF cleaner from advanced auto or somewhere similar. 10 minute job

 

Thanks will give it a go. Where can i get MAF cleaner in the England, dont seem to be able to find it?

 

Probably at any auto store. I live in the states

 

Maf cleaner is the same thing as electrical cleaner.
You should be able to find it at an auto parts store, it's fairly inexpensive.
