Diagnostic or tune-up

[Mrk_Mickey]

Hey guys,

My car has been running like rat-poop recently and I'm eager to get to the bottom of this problem as it's been intermittent ever since I bought the car. It's basically a power cutting issue, where it 'feels' like the car is choking and doesn't want to go anywhere even with the pedal all the way down and all noise apparent.

A few people have mentioned things like a dyno diagnostic, or a diagnostic test where you can go to a dyno place or similar and they can actually check your car out for one way or another, and then possibly suggest either an ECU reflash or a dyno tune to get it running better or something...now I know very little about this so I thought this would be the best place to ask you lot for some advice on sorting out my problem?

Oh and for those who are going to suggest Vag-com... if you actually have vag-com and are willing to scan the car for me then no problemo, but please, if you don't have it and just want to tell me to scan it then don't worry about posting because it doesn't actually help me. (Sorry if that's rude, I'd just prefer technical knowledge/information passed on, not vag-com advice as I'm already aware of that option)

Sounds like you have a hardware issue mate. Unfortunately, the best way to get to the bottom of it is with VAG-COM. There are too may sensors to go through that could affect the engine's running that doing anything else would be time consuming and probably costly.

If you have good plugs and leads then you need to get it scanned.

Dammit...right well who has a propper VAG-COM and is willing to scan it for me??

Yeah, sorry to have to write that. Can you not get to see a specialist?

I'm sure I can, but who, and does it cost anything (gotta plan it if that's the case lol)?

While I have the dodgy eBay knock off, it works fine with the limited computer in the Mk3's Happy to run a scan for you, but at the end of the day I'm no expert... Maybe it's worth taking it to someone who can scan AND fiddle

Normally I would say bring it round on the weekend, but this weekend I won't be here and next week is my mates wedding... But after that...


PS. I have absolutely no good reason for saying this other than because it's the first thing my brain thought... dodgy MAF?

[h100vw]

No need to be an expert, if there's no faults listed check the MAF output on the measuring blocks and see what's being read. Post any codes on here or check the web.

Yeah and make sure the bugger is getting fuel, saw a Maf fitted to one that had a fuel filter you couldnt blow through, exactly the same sort of symtoms presented, wasnt a good look for the guy.
