TCS light on and Engine management light too... ideas?

[Shings]

Hi All

I drove up to stafford last night- 30 miles, no really hammer or owt...
(Leon Cupra - Chipped etc)

When I got there I stopped and then had to move my car and noticed the TCS light on automatically on the dash... then a few mins later the engine management light came on.

Today I discon'd battery and reset it- TCS light still on but no engine management.

Drove to uni 9 miles, parked up- came back to it a few hours later and both on again.

Other than the lights on the dash it still drives fine no probs, full boost etc.

Any ideas???

I did a quick search and it might be the MAF - whats that? Where is it??? apparently disconecting it and reconnecting may solve it?

Cheers all

Prob a dead MAF mate.

For you clever clogs that means loads-haha

I have no idea what that is or where it is or how to check it.

MAF = Mass Air Flow meater. Its the little black tube with a electrical plug/connector on it coming out of the air box.

Try unpluging it and go for a drive, if it drives better then itd deffo the MAF.

It doesn't seem to drive any different mate.... and I dont have an air box- its got an induction kit (was on it when I brought it)

You got a pic so I can go have a fiddle??

Airbox or induction kit, both will be attached to the MAF.

It might be just on its way out. Or could of been breaking down for a while and you wouldn't realy notice it. Its worth unpluging it and see how it drives. At least it will rule one thing out.

Will that switch the lights off on the dash as well??

No. if it is a dead MAF and you get a new one the lights will eventualy go out after a number of ignition starts. But the ECU will still store the faults. You will need to get a garage or some one with vag-com to clear the fault codes.

hi mate,

I have got the same problem both engine management light & tcs light
just came on for no apparent reason.

Me 2 have had on diagnostics machine and came up with MAF = mass air flow meter
and me 2 have got induction kit on.

i have been told numerous things by many different people,
1- try changing MAF
2- try changing abs sensors
3- try changing abs ring
4- try changing brake light switch
5- try changing traction control unit

its ok ppl saying try changing but its cost and these parts arent cheap.
all i can tell you is what i have learned is all above is connected to same
wiring loop so if there is a fault on any of above will bring both lights
on whilest car still runs fine as before.

Hope this helps??? It hasnt for me cos im affraid not gunna shell out on a wym
and going to let it develop as car running fine.

As said, your MAF has failed.
