[QUOTE=ceedy;2877555]As its always been the advice to not touch the Cheap end stuff and get a genuine Bosch , Anyone had experience of the DMGRS cheaper end MAF's.,
Quote the bosch maf bumf on their site "
Cheap MAFs on the Rover 75 / MG ZT CDT / CDTi can cause over or under fueling, poor running and other issues." 
2yrs warranty, & how do you prove its duff but
And @ 55 quid every 2 years isn't that economical .
I got this one a couple of months back, took the sensor out and put into the old unit on the car. Works a treat and if I have to replace it in 2 years time then so be it, a small price to pay for such a cheap unit. Would take 6 to 8 years and 4 changes to reach the price of a BOSCH unit
