Hello there,
I recently purchased a 2004 Rover 75 Connoisseur SE with the BMW sourced 2.0 diesel engine. It is a beautiful car with a lot of life left in it; but I have been facing a few performance issues lately; and I was hoping to get some advice from the knowledgeable members of this forum.
The car starts fine and runs smoothly most of the time; but occasionally; it seems to lose power when accelerating; especially on inclines or when overtaking. It feels like the engine hesitates or stutters for a few seconds before picking up again.
There are no warning lights on the dashboard; and I have had a local garage check it over; but they could not find any obvious faults.
Despite these efforts; the issue persists. I have read online that the EGR valve could cause similar symptoms if it is clogged or malfunctioning; but I am not sure if that is the case here. Has anyone experienced similar issues with their Rover 75?
Also; I have gone through this post; https://www.rover-forum.thersr.co.uk/viewtopic.php?ccsp=4407 which definitely helped me out a lot.
Could it be something as simple as a clogged fuel injector or perhaps something more serious with the turbo?
Thanks in advance for your help and assistance.

Re: I Need Advice on Rover 75 Diesel Engine Performance Issues
Hi Padrickk,
It's possible that the in tank fuel pump could be on it's last legs, causing low pressure in the fuel system, it could also be a partially blocked diesel filter (this is in the engine bay) it could also be the Mass Airflow Sensor, these are known to drift out of specification as they age, unplug it temporarily and then see if the performance improves, if performance improves then you'll need a new MAF, use the genuine Bosch item as a replacement, cheap Ebay specials don't last and usually fail in a short time, DMGRS (Discount MG Rover Spares) have the genuine article here: https://www.dmgrs.co.uk/products/rover- ... ab59&_ss=r
I'd recommend joining the Rover 75 & MG ZT Owners Club (https://www.the75andztclub.co.uk/) where you'll find a wealth of technical knowledge and helpful members to help you keep your 75 running, I've been a member since 2006 and I find the club invaluable for sourcing information of maintaining and repairing the R40 range of cars,
Regards,
Steve
