I'm having a few problems with my car at the moment and it just seems to get worse by the day
, so I'm hoping you knowlegable lot will be able to help me out a bit!
I'll start at the beginning.
The car is a 2001 Leon Cupra 1.8 20vt (180bhp). It has been superchiped, has a pipercross viper closed cone induction kit, a Scorpion Cat-Back exhaust system and had the head polished although this was a while ago. I have felt it hasn't been running right for a while (Seemed to be lacking power, can hunt for revs at idle sometimes mostly after its had a bit of stick and just doesnt seem to be running as smoothly as it should sometimes).
Anyway, I put it on AET turbos dyno yesterday and it produced 160bhp and 155lb/ft at the flywheel, it was also producing standard boost and running too rich. This is well down on what i was expecting but at least I definately knew something was wrong!
Andy at AET advised me that first port of call would be to speak to Superchips as he thought the chip may have been written over or was causing some other problems, other than that he also told me to have a look at the coil packs and MAF aswell.
Guy from VES superchips came out today and after a bit of head scratching and having to send a copy of the MAP back to Superchips, confirmed that it was installed and working correctly. However, he did tell me that my dump valve wasn't working! It's just the standard Bosch DV and he tested it by sticking a bit of pipe over the top small outlet at the top of the DV and sucking air through, apparently he could feel fresh air rather than it creating it Vacuum which told him it was knakered
I've got a Forge one that i'm going to try on it tomorrow but surely a simple boost leak from the dump valve can't be responsible for loosing the best part of 50bhp can it???????
He also created a new problem before he went, he had taken the airbag fuse out when he was messing about up-loading the map, when he un-plugged everything the air bag light stayed on
Tried to reset it a few times but with no sucess, it was fine though before he plugged into the car so surely it can't be a wiring fault or anything as this would have shown up before now??? Bit nervous about driving around at the moment if the airbags are not working as I do lots of miles and it doesn't take much to have an accident!
Apologies for the long post but I'm at a bit of a loss of what to do tbh as I've just been made redundant so I don't have loads of money to spend trying to fix the car and most of the stuff seems to be trial and error (Coil packs and MAF). I just want to get the car running back to its former glory again and hope someone will be abe to give me some ideas on what the problems are likely to be or what my best course of action should be.
