*Help Needed* EPC and Traction Lights. Fuel Cut/Limp Mode.

[monte]

Well my car has always run real strong and never skipped a beat. I recently fitted an S3 Intercooler and changed my spark plugs to Nology Silver.
About 3 times now on hard acceleration the car has coughed and bogged down for a sec and then picked back up as usual.

Today however I was about 10miles from home and it did the same. 

Thinking nothing about the "Fart" I had a nice spirited drive. When it came to some hard braking I noticed that they faded abnormally quick. (S3 brakes all round) I was more than a little concerned.

Anyway I took it steady as I was nearly home.

Curiosity got the better of me, and I thought I'd see if this Fuel cutting out "Fart" was still present.

I have it some gas, and once again it bogged down....but this time it stayed like this. (Limp mode)

The EPC and the Traction lights lit up on the dash and stayed on the rest of the 3mile journey. 


Anyone got any ideas/advice?

Should I have had my Revo settings adjusted to allow for the S3 Intercooler?

Why do these things always happen on a Saturday/Sunday when you can't get it looked at for days?

Check the IC pipes on both sides, check you have the rubber seals on them too.

When i fitted mine the day after i blew the hose off (causing car to die, warning lights and such), and it was because i didn't have the rubber washer on (aherm....)

You really need a vcds scan and pray that it's not your abs unit that's packed up.

ah mate hope you get it sorted soon...

could it be a coil pack, did it seem as if it was running on jungle juice?

sometimes when adding new bits, it does no harm to disconnect the battery for 15 min for a reset...

I bet you have this fault code, just like I suffered last night:



It means you will need a new throttle body.

I would find it odd for it to be the ABS pump.
Everyone screams about it but to be honest it's like £200 to have fixed these days, not a lot of wedge, certainly not the £1000+ shockers people are spreading.

When you noticed the little coughs did you notice the traction control light?
Give it a scan with Vagcom and see what the car THINKS is wrong.. and work from there using logic.

  Sounds Expensive Alex!!!  

Is it a common thing mate?

It's been running fine Neil, well apart from the 3 or 4 times it bogged under acceleration.

TBH Doc, I was a little worried it might be an ABS issue.  

Ill try and get a scan done tmrw...if not Mon/Tues  

Check the IC pipes on both sides, check you have the rubber seals on them too.

Ill check them out Ed  
I want to rule out as much as I can.

Cheers Buddy Will do 

(I didn't notice any lights flash on the dash when it coughed.)

With a throttle body problem, when would it cut the fuel and how would you know.>

hope that doesn't sound like a silly Q?

[rich83]

Throttle body is a 400quid fix...

Sounds like it to me from what your describe... you need to get it scanned as said above.

Feels like you hit a wall when at full throttle at about 4000-5000RPM... followed by EPC and traction light on the dash

[scopes]

so there would be a drop in power?

[rich83]

so there would be a drop in power?

Yes... its immediate power loss. Followed by limp mode.

Where in Lincoln are you Monte?

Believe me Neil you would know. 

As you accelerate hard, you are pulled back into your seat, then when the fuel cuts out you are thrown forward like you have just pressed the brake.

The fuel only cuts out for less than a second so then when it picks up again you accelerate as normal, pushing you back in your seat. 

Where in Lincoln are you Monte?

I'm in Saxilby Jim (just off the A57)
