car scanned coolant pump open circuit

[Petecog79]

Error first came on 6 am in the morning. Car had been stood 12 hours

The reason it came on at cold start was the car was hot when parked up and the ignition hadn't been turned on again so that was the first chance to show the error.

Any ideas on best place to get one or is it main dealer only

 

[Marshall]

The link I posted above would be my first choice!
Unless you want to pay another £60 for the same thing?

Spot on mate ive ordered one

Does the pump have anything to do with egr as I had my egr mapped out

 

[Marshall]

Not as far as I'm aware

Pump arrived today will fit this week . Just noticed the flat spots I had in third n fourth at 4k have gone since eml on!

 

[Petecog79]

Pump fitted. If it for some reason isn't the pump how soon will if be before eml.comes on. Ive used car twice now 3 hours apart and didnt hold back on throttle, so far light is still off. When I removed pump there is something rattling inside, gonna strip it and have look.

The impeller was seized on mine!
You'd know within a day or so. When the cars warm and you switch off you can feel if the pumps running.
It'll be sorted now and at a cheaper price

 

[Petecog79]

Cant feel it running but no light so far. Stripped pump not much inside to go wrongbonly one moving part thr mahnetised impeller, electronic control sealed but looks brand new!

 

[Petecog79]

Mate no way impeller can seize it sits on magnetic coil totally sealed unit ie. One moving part! Which cant fail unless rusted

How have you gon't on with this and how easy is it to swap as i might have the same problem. I had a coolant fault that i cleared and came back after a long run and on starting the engine i will make sure it's the right code before i commit to buying nay parts though.

 

[Petecog79]

Car is sorted mate had first fault code as coolant pump open circuit I cleared it and it came straight back on. Checked the code again but only had a universal scanner which gave code 9754 which is exactly same fault. I ordered pump after looking at code on faulty pump. V easy to fit just take undertray off and its right in front of sump. Clamped coolant pipes and removed pump then fit the new one. Two pipes and a connector. My pump came with new bracket attatched which I removed as its easier using existing one. Only one minor prob is I used pliers to remove 3 torx screws that hold pump to bracket as no room to get one if them out.

Thanks for the info, i have a VCDS cable but will check as i think i have the same issue. Car is a 10 plate so i am hoping it's not the start of things to come
