Are you suffering from loss of power??

Rite just thought I'd help out any newbies or people who are a little unsure why there car won't go anywhere

First thing to do is get the car on a diagnostics machine, vag-com or VCDS I'd the best but you can get code readers from eBay that are of use vag-com is available from Ross-tech.

Usuall suspects to check

• Boost leak
Check all you oil breather system pipes for splits breaks ect

Check all the vac pipes -locations of some- under the in inlet manifold - on the N249 (if you have it) - on the dump valve/ recirc valve and a few more think

Check all the boost hoeses - and the tip (turbo intake pipe) most of the boost pipes are straight of the turbo & DV

If you have FMIC fitted the check the pipe work for this as as if lies or I'll fitted then will cause a vac leak

I also think that you can get them from master cylinder and a few other places witch I'm hoping people will add

The best way to keep an eye on this is to fit a boost gauge to keep an eye on what you boost to and what you vac is at idle
Standered boost is about 9-12 psi I think and on idle the gauge should read -22/-24 vac
Solution- have the car presure tested at you local vag specialist to locate any if all the leaks and replace apropeat pipes ect

• coil pack

Firstly do you have any dash lights on? Does the car sound like a scooby? Do you have a slight miss fire? Or does it miss fire alot? These are all signs of coils packs gone

Solution- have the car scanned on vagcom and replace the apropreat pack or if you can replace all four!

• Faulty MAF (mass air flow sensor)

This can bring up a traction control light either constant or on a MAF that's starting to go an intermittent one. Also the wiring on the sensor can cause this if is cracked or loes.

Solution- unplug the MAF and take the car for a quick sping and see if it performs better? If so then buy a new MAF not a cheep one tho

• Dirty throtle body

This can cause the car to under perform

Solution- 1 get some carb cleaner take of the inteercooler to throttle body pipe and spray it into the throttle body while reving the car
2 take the trottle body off and clean it by hand then replace and reset via vagcom (guides for this can be found via search)

• A broken turbo

Normal signs of this are blue, White or black smoke in excess, major loss of of power, turbo making strange noises and turbo failing to spool

Ways to check it are remove charge pipe (the one that comes off the turbo) and check for play in the turbine excessive play is not good have tge car checked out by you local vag specialist.

So far that's all my little brain can think off if I've missed ANYTHING or got anything wrong then please let me know
If you can add anything to this then post it and I will edit it in

And lastly I hope this is of some help and I'm sorry for my spelling

Cheers all
Sam

no wories fella I'll keep it updated with any new info and probes add sone pics

Not to question your knowledge but is it true that the traction control light can flash on if the MAF sensor is faulty?

Should have mentioned my lcr seems to lack its original power from when I bought it. I will do some of the checks mentioned , thanks

Yes the traction control light will come on if the maf is faulty mate for some reason the maf and the TC run on the same warning light

But this is not always the case sometimes you won't have any warning via the dash just that the car runs crap

If you read the first post I do say that it can bring it up and the one you quoted is just confirming that it can

Batter???????

Was just confirming it will not in all cases but it will

nice work sam, had the car up at bills??

Na Dailynks, going to bill next payday for pressure test and blueness it's boostin better but still not to it's best, It will every now and then and fook me she flys I've got more to add to this thread, N75's ect and pics just need the time

read your post back to ya self mate, let me know when your sorted and i will try and read it again, remember im from Oxford... i dont understand swindon lingo

just thought of some thing to add
if you have had the REVO trial map put on your car... when it goes back to standard it will/does feel under powered, it WILL BE, they couldnt get the standard maps rite, personally i think its a con but hey ho, was a good idea i spose for them, i know a couple of ppl its happened too both went back and both came back with the same answer and both eneded up shelling out for the map...

Wasnt a trial map was stage two map I've used my sps switch to turn it off and gone back standard and there's s big difference Got the receipt for the map was £600 lol I edited my last post any better old man

much better duck
i dont know what they use as the trial, just know that it goes back to below standard, there is a thread on here some where too, dont ask me where though
