Fault 01435 ATE Teves mk60 ABS economical time/cost repair

Dash warning light appeared last week and abs and esp lights are on.

Got a scan done: 01435 Brake Pressure Sensor 1 (G201) Electrical fault in circuit.

After lots of research it seems to be a common problem across VAG group cars and others.

I am going to change the brake light switch in the next couple of days just in case, but have been advised this is unlikely to solve the problem. The brake lights are still working. Do I have to have the fault cleared from the memory to find out if this has been successful?

It seems I can get the abs unit repaired at BBA-Reman or ECU testing who are both charging £165+VAT but neither can do this on an exchange basis, only a repair your own unit in 3-5 working days meaning we are off the road for probably a week.

Does the club or any member have a defective unit that could be exchanged so the job could be done in the day?

My unit is 8Z0 907 379D

I intend to have a local garage do the changeover as I am fearful of bleeding the brakes afterwards. I have no diagnostic equipment. Or is it easier than I imagine?

Tried one local independant garage who explained they don't touch A2's! "When they get to a certain age"
 
See the below notes from Ross-Tech Wiki:

01435 - Brake Pressure Sensor 1 (G201): Electrical Fault in Circuit
Possible Causes

Brake Pedal Switch (F) faulty/jammed
Brake Pressure Sensor 1 (G201) faulty

Possible Solutions

Check/Replace Brake Pedal Switch (F)
See Measuring Blocks
Check/Replace Brake Pressure Sensor 1 (G201)
ABS Hydraulic Unit (N55) may need to replaced
Perform Brake Pump Bleeding
Perform Brake Pressure Sensor 1 (G201) Basic Setting
Replace Brake Electronics Control Module (J104)

Special Notes

When found in MK60 ABS/ESP Brake Systems:
Check if the Repair Kit documented in TPI 2024465 or 2025290 with the Part Number 1K0-698-517-B is compatible, using the Repair Kit allows to replace the Hydraulic Unit (N55) and the Brake Pressure Sensor 1 (G201) separate from the Control Module which will reduce the Repair Costs.

I've got one same code off my 2004 TDI, inbox me and drop me a line if you want to exchange it. You can send one off for repiar whilst still using your car, once it fixed and fitted, send me the defective one back.
 
I’d be tempted to change the brake pedal switch first, and if you have access to VCDS you could clear all fault codes, run through the ABS output tests and see if the error re-appears.

Thanks for the advice, I will get the switch swapped over the next few days (dealers are being useless at getting the correct one into stock), and let you know if I need to take up your generous offer of a temporary exchange unit. Thanks. Adam.
 
Update HELP!!!!
Car dropped off with local independant german specialist last monday 20th. ABS unit sent to BBA reman. Returned Mon 27th. Cost for repair £147.
Unit fitted and problem sorted. Hooray!!!
But mechanic cannot bleed brakes, has spent 3 days and 9 litres of fluid trying! Collected car this evening still with long pedal. Car will stand on it's nose but only at the bottom of travel. Have been advised to use it to see if that dislodges the air, and return saturday morning for a while you wait rebleed. Am a bit dubious.
Anybody have any experience bleeding ABS unit. Help!!
 
Here we go:

01435 Brake Pressure Sensor 1 (G201)
012 Electrical fault in circuit.

I've got the same issue here with the ABS and ESP lights coming on and then when you start driving, the red brake warning light in the middle of the diplay lights up with three beeps. Fault code as above. G201 sensor is reading ca 214 bar and is obviously at fault here.
Looks like I need to get the unit out of the car and send for repair. Just checking in here if there are some steps that should be followed when working with the ABS unit or if it's just a matter of getting it out of the car and back in and then the bleeding of course.
 
Thanks, Spike. I have a 2005 so it's the MK60 with the built in sensor unfortunately.
I'm doing some prep work now to get the unit out of the car and will probably send it all the way to BBA-REMAN UK from Sweden since I can't find any local shops here that is even close on the price. The standard price here for a repaired unit is about 3 times the price of ECU testing. Haven't got a price yet from BBA REMAN but I guess they will match ECU testing.
 
So I got the part back from BBA-REMAN and fitted it to the car and all is well.
However there was a note that came with the unit which said "Customer needs to reset adaption to car".
I have a friend with VAGCOM that can help me with that but he needs to know what the adaption value should be set at so looking for information here. Anyone know what it should be?
Kind regards,

Hans
 
From what I understood, & I may be way off beam here!, the unit needs to "read" (statically) all it's sensor inputs from steering angle, yaw, wheel speed etc etc so it can use them as a baseline for when these self same sensors are giving data that indicates things are about to go pear shaped. So its not a "value" that you manually input.

But I haven't a clue how you would initiate this "read" I'm afraid. Having a google for tevez sensors and vcds make come up with something in a quiet backwater of the interweb.

I really do not know how this "adaption" is done so any help appreciated. I'm looking all over for info on this but have come up empty handed at this time. At least I got the unit fitted without issues and all warning lights are off. Adaption comes next.
Thanks.

Can't find anything on 'adaption' but if a new ABS control unit was fitted then it would only need coding. If your original unit was returned its possible the coding is still there and no fault codes would be logged.
Ideally, if you have an old diagnostic scan the coding will be shown under Address 03 - ABS Brakes.
My MK 20 unit is coded 10758 and I suspect the MK 60 will be the same.

Cheers Spike
 
Thanks guys.
I think the first step will be to connect the car to VAGCOM and see if there are any issues present and take it from there.
It is the original unit. Before I sent it off I made small marks on every detachable piece that only I knew were there and I have confirmed it is the same unit that I got back. Seems to me that adaption is what is described as "Basic setting" over at Ross-tech wiki but I could be wrong.

Kind regards,
Hans
 
Hi,

the coding on the MK60 is different to the MK20 and also different for each engine type.

According the VAGCOM, the coding for a TDI 75 on the MK60 8Z0 907 379 D would be 0007303.

The procedure described may refer to "zeroing" the sensors (steering angle, brake pressure etc.) which is normally done when a part is replaced. The procedure differs for each sensor, but you will need VAGCOM to do it. You basically put the car in the position where the sensors should read zero (level road, steering wheel straight ahead etc.) and then issue the codes to zero to that reading.

regards

Thanks Andrew.Just read about Adaption in the vagcom system in the link below and that is absolutely not as straight forward as a "Basic setting".I may have been wrong assuming adaption was the same as a basic setting. There is really not much info about it. I am starting to question BBA-REMAN's note that adaption should be needed now. It may need a basic setting, but I can't really tell at this time. Well, here is the link to the adaption process over at ross-tech. http://www.ross-tech.com/vcds/tour/adaptation_screen.html
