Garage tells me I need a new ABS unit on a Mk1 Octy L&K 1.9TDI.

 

(full story here) 

 

No 1J0698417A in the UK they tell me. Backorder item.

 

Anyone know the difference between  1J0698417A  and a 1J0614417D ?

because I can find those.

1J0698417A is the replacement for 1J0614417D, but the reverse is not true. YOU CANNOT USE 1J0614417D IN PLACE OF 1J0698417A.

You may be able to get your unit fixed by a company such as http://bba-reman.com/uk/ and they may have a remanufactured one in stock.

Cheers for the reference. That helps.

 

In the first place, a 2002 Octy does NOT have ESP. It has ABS, and ESR, which works by using the ABS sensors to detect wheel spin and cutting back the throttle when it does.

 

Secondly, DO NOT pressure bleed a VAG ABS. Use a vacumn bleeder which removes the risk of introducing air bubbles to the ABS valve block (and the rarer risk of inverting the master cylinder seals).

 

Since you have pressure bled the brakes, I'd suggest that your next moves are to acquire a vacumn bleeder and VCDS, and use them to bleed the ABS block.

You can use a pressure bleeder but you need to keep the pressure at 1 bar or below when bleeding the brakes to avoid 'upsetting' the proportioning valve. In the linked thread, the dealer has already done a diagnostic bleed so using VCDS won't help in this case.

Your going to want a used one as new they are close to 1K GBP. Used, found two in Germany

Fantastisch, Ordered one.

It's a Laurin and Klement ... I think it has ASR. It will light up with a picture of a wheel in dash when I take a hump backed corner in dry conditions at silly speed. I don't do that often.

Thanks,

Bloody Haynes manual only describes old fashioned two man method or a pressure bleeder, not a vacuum bleeder.

 

Air is compressible and brake fluid will displace it. How does air ruin the ABS block?

Typo/brain burp - I meant ABS + ASR. Either way it's traction control and not ESP. If the garage that says you need a new ABS also said you have ESP, then that calls their competence into question I think. 

 

Pressure bleeding can lead to air getting forced into the valve block on the ABS controller, where it gets trapped in the valves. The VCDS bleed function exercises the individual valves to pump the air back out, which a straight forward pumping of the brake pedal doesn't do.
