A4 1.9 TDI 03 engine not warming up.

No, fans operated correctly for me. I am talking about the thermostat housing. It's around £10 from Audi. Thermostat is around £40 from Audi too.

The problem I think is when you take the old stat off to replace it, the housing tabs tend to break. So change the housing as well.

If your fans are working all the time, might be related to CTS.

Ok, cheers. I'm going to have to leave it till the weekend before I can get to a garage. Bit apprehensive about having to drive it up and down the motorway till then. Was a bit of a shock when it died on me today!

Another issue! The ABS and ESP lights came on during the trip home. Drove ok but wasn't sure if id have another power loss. Made it home, did a little research and it appears to be the break light switch which is causing those lights to come on. Is it OK to drive with those lights on tonight and get it fixed tomorrow?

Think it's more likely to be an ABS sensor or cable than the switch, how did you reckon it might be the switch? You won't have functioning ABS while the light is on.

Googled it. Turn ignition off and it clears the lights. Can make it happen again by pressing the brake pedal.

fair enough - I've had to do a pedal switch on the touran and polo, seems to be a common enough failure but cheap fix.

**Dubbs75** · 14-04-2016,08:52 PM

So if it's the brake pedal switch can I drive it? Only reason I ask is my daughter is currently at a concert 30 odd miles away and I was supposed to pick her up, might be a taxi instead!

**Rob69** · 14-04-2016,09:03 PM

Sorry bud, can't answer that one for you , your call.

If it was me though, and I was confident it was the switch and everything else was ok brake wise, I probably would.
Does that cover my **** enough ???

**Dubbs75** · 14-04-2016,09:06 PM

Fair enough mate. I'm probably not going to risk it. Knowing how things are going at the moment, it'd only break down on me!

**Dubbs75** · 15-04-2016,07:51 PM

Got some codes.
P1586 left/ right hydrolic sensor

00526 brake switch

Garage want £580 Inc labour for the hydraulic sensors. Said they can't just replace those, it's a whole unit. I'm not convinced so going to a different garage tomorrow. I still think it's the brake pedal switch.
