Golf VR6 OBDII diagnostic code help!

[roosevelt]

I have an Engine error code 533 - Idle Air Control Regulation and ABS error code 1276 - ABS Hydraulic Pump-V64. Now I have the codes can anyone help with what remedial work is required?

I erased the ABS code (MOT due!) which turned off the ABS warning lamp until the next time I used the brakes!

With regard to the engine code I have a mesh sports filter and s/s sports exhaust, otherwise engine side is standard.

Help!

What diagnostic system did you use? Was it VAG-COM, or VCDS as it's called now?

If it is an OBD2 Golf (96 on) then the Idle Air Regulation error points to a problem with the throttle body. It has a stepper motor inside it which opens/closes the throttle plate to regulate idle speed.

Try cleaning it with some brake cleaner first and check none of the wires are chaffed, broken etc etc.

If no joy, replacement may be the only fix and at £300+VAT from VW, you'll probably be wanting to look for one on ebay instead.

The ABS error is more of a concern as it's fault coding the pump itself, which again is a hideously expensive part new.

When was the last time the brake fluid was flushed through? Sometimes the pumps in the ABS unit can get sticky with age if the fluid isn't regularly changed (every 2 years). Try that, check the usual wiring and make sure the ABS ECU has got damp etc etc.

Hi it's a 1997 MY, so OBD 2. Will check out throttle body as advised.

RE ABS fault code, brake fluid has been changed every two years for last 10 years, will check wiring on this.

thanks

Re ABS twas the ABS pump. found a s/h one 50 yds from the garage where car was investigated for £50. God bless ebay!

As for throttle body, this is pending investigation...............
