Fitted the Bosch 0 392 022 002 charge cooler pump today as i suspected the old pump was not working. Fitted pretty well with a bit of trimming of the original rubber mounts
The old pump to my surprise did run but must have been on its way out as the charge coolers were getting so hot I couldn't touch them plus kept throwing a P2601 code. Tested the new pump before Installing and it howled compared to the originals slight whimper
45 min test drive to make sure all was ok and can't believe the difference Front of the coolers almost cold and the rest just warm Water temp monitored via the ETM was running at 95 to 98 degrees now running at 92 to 94 even when pushing hard. I'm starting to suspect that the pump has not been working well from the day I bought the car as performance was significantly improved
Best £75 I've spent in ages Anyone needing a new pump forget the Hella and get the Bosch
