TCS light staying on

[gazbrum]

As above the light is staying on after switch car off and restart it stays on automaticly. Usualy as we no we have to click the tcs button to turn off the TC and a yellow light appears. well its contantly on , it also made my EML to come on but i reset battery and the EML dissapeard. wonder what up?

I fitted my new coilovers recently and my traction light is also staying on. Car is running 100% the same as before, braking the same, but no faults came up AT ALL when I put it on vagcom and no EML....weird.

These leons can be weird with the EML sometimes lol. has any one every had a problem when switching air con on and the car runs a bit lumpy revs going up a down alot?

 

[Hilla LCR]

I think that happens in most cars to be honest, my dads astra is really bad for it, sounds like it's gonna stall lol

The compressor will put the alternator under more load than it wants to be when at idle, which is why you get the uneven idle.

I regards to the first post, I was lead to believe that traction control staying on was usually a knackered maf sensor, your eml will be off if you've left the -tive terminal off the battery as this will clear the codes, although I would highly suspect them to come back sooner rather than later.

the tcs/esp light often shows when the maf is on its way out as said. EML light means the ECU has logged a fault and needs reading with vagcom or similar to find the fault code.

is the car running right? if it idles poorly you could try disconnecting the electrical connection on the maf tube, if this instantly improves the engine its 99% the maf sensor

^^^^ Just went and checked this on my car, made it a lot smoother on idle! Thanks a lot!

 

[traumapat]

new maf for you then

dont run it unplugged for too long as it runs rich and can damage the cat.

 

[Hilla LCR]

Yeh thanks pal, I'm gonna take it easy until I get a new one, where would be the best place to get them from?

I've just had a quick look on GSF and there's quite a few different ones/makes. I've done a quick search but couldn't find a specific part number.

 

[lee_woollett]

take the maf off, the part number you need is on the underside of it. i got mine from gsf on yesterday. excellent service. i ordered over the phone.

 

[Hilla LCR]

Thanks mate, will get one ordered tomorrow

 

[gazbrum]

how much are these mafs. is the maf that connects to the aifilter and somat plugs into it?

mine is doing this too. what could it be

 

[sexynips]

are pattern mafs any good or should i get a genuine one?

 

[greesha]

Only use genuine bosch ones. Around 65 quid if i remember from GSF (regenerated - when you give your old one back)

 

[kineticz]

Mine's just gone too lol, must be the weather, will be calling GSF tomorrow.

 

[gezmeister]

£70 from GSF

 

[kineticz]

£70? Is that delivered? On their site the MAFs are all around the £50 mark?

 

[gezmeister]

I went in last month when mine failed, £95 including surcharge and £25 to come back, so £70. I know that the 150bhp engines are cheaper?

 

[kineticz]

Ordered over the phone today, sensor came to £61 plus £29 added until I return the old MAF
