P1641 Fault on the pairing ASB/ESP

Post by neilrc30 »

I am after some assistance with the above Fault Code. My ESP light is on permanently and the enable/disable pushbutton light is permanently on too. The Fault code is P1641 message Fault on pairing: ABS/ESP electrovalves / hydraulic valve block. I can't find any info online for this error code. Any assistance would be appreciated

You'll need to post your VIN (Automasked on post submission) so I can relate the error directly to the specific ESP System you have on your car.

Vin No. is VF7**************[VIN obfuscated, can be read by forum staff]. It also does not recognise the ESP/ABS ECU when i interrogate with Diagbox it gives me the option of two - ESPMK60_0? and ESPMK100?
To give it more background, this has stemmed from a more serious issue the engine light came on and the car goes to limp mode. A garage spent alot of time (£1300) getting nowhere and replacing stuff. I then replaced the MAF, fixed a connection issue with the air manifold and changed, for the second time a new Fuel Rail pressure sensor as i keep getting P0193 Measurement of the fuel injection pressure Short circuit to positive (wiring checked ok) Pressure too High. The car is fine when i reset errors until i drive it, as soon as i get 200 yards down the road engine light comes on and i get the fuel rail pressure fault and sometimes air flow. I also get the faults below. Though i now have a permanent fault on the ESP/ABS pairing P1641 which i cannot clear, which was probably down to me after playing with diagbox

I am sorry for the long winded message hopeing you can advise on the issues individually. I have spent hours on top of the time the garage have, including buying a secondhand Engine ECU/BSI/Key Fobs, which gave me the same faults as before.

I also get the following errors with the ESP/ABS ECU after i have run the car and the engine then goes into limp mode:
ESPMK60_0:
C1391 - Fault non-confirmation of engine torque
U1208 - Communication missing fault with the engine ECU
C1641 - Supplier Fault Code

ESPMK100:
C1391 - Fault non-confirmation of engine torque
U1208 - Communication missing fault with the engine ECU
P1641 message Fault on pairing: ABS/ESP electrovalves / hydraulic valve block

Any help would be appreciated as i am at my wits end with this now
