ESP and ABS lights again!

Driving home today, I got the dreaded amber ESP and ABS lights with DIS message that I am oh so familiar with. Got home, scanned with the Carista and fault codes as follows;

01276 - ABS Hydraulic Pump (V64)
01314 - Engine control module (ECM)
01826 - Sensor for steering angle (G85), Voltage supply terminal 30
01206 - Signal for duration of ignition off time

I have had the 01276 code in the past, about 4000 miles/5 months ago, but this was fixed by the dealership that I got the car from redoing the basic adaptations for the ABS module (they had replaced the ABS pump before I bought the car).

I have reset the codes, and the codes did not reappear immediately, but I will monitor this - I didn't go out for a drive after resetting, was just curious if they would reset. Its a bit strange though as 01206 is a climate control code, and the other 3 were under the ABS ECU category on the Carista app, so perhaps 01206 is unrelated.

I have read on the forum about low batteries causing strange behaviour and electrical issues, but I got my battery tested while I was having my thermostat replaced a couple days ago, and all was fine with the battery.

I want to say that 01826 was the main issue code, and 01276 and 01314 have come on off the back end of 01826 going off. My steering does feel fine though, as does the rest of my car (at least it all felt fine on the 3 miles to home following the code!).

Does anyone have any experience with the above codes? Would be interested to know if anyone has had similar issues in the past, specifically the 01826 code, and what could have caused it - RossTech suggests steering adaptation may be required, and worst case scenario its the steering column control module!

Even if its just a one off blip that does not occur again, would be interesting to know why it happened in the first place.

Appreciate your guys help as ever, cheers!

Have you checked the physical condition of the angle sensor itself? I seem to recall this topic came up in the past and was due to the sensor being damaged from road debris that somehow hit the sensor.

A bad connector can also cause problems if it's damaged or if there's any contact corrosion.

You can find this covered in the workshop manual Suspension, Wheels & Steering - D3E80075730 listed in the KB.

A quick search for "steering angle sensor" may help you find older posts on this issue.

I feel your pain. Ongoing for me also, I was going to buy a recon ABS pump but looking through various forums and seeing that the steering angle sensor can set off ABS and ESP.

Can't find a definitive answer on whether Vagcom is needed or not, after manually resetting the sensor? I also use Carista and a few weird codes came up like Body Convenience whatever the hell that is?!

Had a sticking p'side caliper and replaced that and cleared codes, thought I'd cracked as the ABS/ESP stayed off for approx 10 miles but alas came flocking back on.

Infuriating cars, problem after problem, will never have another Audi again. Calipers seizing like they're on some sort of bloody relay race atm just to piss me off even more!

So far so good for me, I haven't got the courage to get to my steering angle sensor, though I haven't properly looked and thought on the difficulty of getting to it.

I've driven a a bit since I reset the codes, and no reoccurrence yet. The steering angle code can be caused by temporary power loss to the sensors so that might have been it I hope.

Lo and behold. ABS light is back.. However, this time it is just the 01276 code.

Think it might just be a ABS pump refurb job. Sigh, why does my TT keep eating my money? I have found a place down near Devon that can refurb the pump for ÂŁ185 +VAT, or can do a drive in and drive out for ÂŁ200 more... 300 mile round trip though.

Edit: just rang ControlUnits and they sound pretty clued up, as you would expect for ABS pump repair specialists. They have apparently done many ABS pumps on TTs over the last year, both mail in and drive ins (and this probably isnt BS as there is 2 google reviews mentioning Audi TT and 5 stars). They say the 01276 code is caused by bushes in the pump motor wearing out (or it was something along the lines of this), and that there is also a wire in the unit which requires repair.

I've had the same issues, code 01276 and I had to replace the ABS pump. The 01826 code for the steering angle sensor should clear itself when driving or you can calibrate the steering angle with vcds, although the codes kept returning on my car and the ABS lights never went off. Its woth checking the fuses at the battery for cracks and the connection to ABS pump as a last resort.

I've booked my car in for Monday for a drive in ABS pump refurb. Here's hoping this will be my ABS issues sorted once and for all. Its a 160 mile drive back home, so will report back on Monday if the ABS is fixed.

(Might also have them take a look at my DGS mech unit which I've noticed tends to kangaroo a little on the lower end of 2nd gear.... Eek.)

Keep me posted. It's not that difficult to do yourself mate, someone on here has a quick guide on YouTube.

Def noticed my lack of ESP, overtook in 2nd and floored this evening and it danced all over the fecking road and still spun up into 3rd when I tried to cover my embarrassment :eek:

Convinced it must have been mapped at some stage in the past!

@ NotTayyeb - Just a suggestion when you take the car in, ask them to run a fault scan when you get there and print it out so you have it in hand. Then you will be able to see any faults that are present. When you pick up the car, ask for another scan to verify all the faults were resolved and cleared. This just keeps everyone honest. A reputable shop shouldn't have any problem doing this for you.

You don't need vagcom mate, I bled my whole system the old fashioned way with a piece of tubing and a small plastic container, just takes a bit of time and patience.

Mine sometimes goes away when I reset it with Carista comes back within 10 miles or so and other times it won't clear at all. Its come up with the message 'cleared but came back' at times also.

So maybe my ABS issue isn't quite as bad as yours. I drove about 30 miles today and around 30 miles yesterday and my ABS light hasn't reappeared just yet. Slightly worried I will turn up at the ABS refurb garage and my car is going to be happy and without fault code.

@Swiss, that is pretty good advice and I might just do that, but I am not too worried as the garage offer a 5 year warranty on ABS refurb a, and all reviews of them suggest they are really reasonable, so I am not too worried about them rectifying any issues which they may cause.

Maybe yours is at the very start of wearing bushes? That's a good price for those units, I've seen breakers selling for double that exchange price, sold as seen!

I still can't get mine to lock up thrashing the brakes on, on an empty motorway. Surely the faulty ABS unit would allow it to skid??? Leads me to think its an electronic circuit problem?

Did you find the source of your coolant leak after your garage replaced your cooling pump?
It wasn't the cooling pump, it was the thermostat housing (I'm prepared to be told they're the same thing). When I gave the car back to them, they had it for a couple hours and they put their hands up saying it was the new thermostat seal that was getting crushed, so they rectified this at no cost to me. :)

My one is very weird. I haven't had an ESP/ABS warning light for about 300 miles now.. I've had stability control kick in a bunch of times doing is quick flashes while I spin the front wheels on ice, thought haven't tried stressing the ABS specifically yet.

Kind of glad I didn't rush to get my ABS pump refurbed before Christmas - I will probably wait for mine to get about as bad as yours before I refurb to replace the motor brushes. Just going to hope I can get it through the MOT end of this month without the warnings coming back!

(Edit- convenient, the ABS warning light came back on my drive home now.. roads were dry, no frost.)

I think I'm going to take my unit out and take it to a general electronics repair shop, Wheeler Dealers had an Avant on the show and the binnacle needed repaired but nowhere in the US specialised in them so Mike got it done at a TV repair shop for absolute peanuts.

It's a pisser having to fork out 360 quid for a recon unit whenever it's an obvious circuit or wiring problem! My traction works perfectly also when I manually engage it before the fault warning pops up.
