How many miles are on it? Has it had the fluid replaced before? I'm having a very similar problem with the same ZF8 in my 335d at 70k and the general consensus to speaking with a few people who have had the same issue is that a fluid change should fix it as they're pretty tough boxes but do exhibit funny things like this when the fluid's cooked. Mine started at about 60k but with how I drive it I imagine the fluid is pretty black and I'm hardly surprised that it's crying enough. I'd get it megaflushed, or even put a new sump and fluid in there. Places like Autodoc sell genuine kits for c£250 at the moment. |

Suggest getting a proper gearbox service at a ZF approved automatic gearbox garage that uses the official ZF fluid. If it's a gearbox fault they will also be able to diagnose it for you. 2012 TDV8 Vogue (L322) |

Also, ‘gearbox oil & filter change’ only equates to approx 30-40% of the oil contained in the gearbox. Quite an emotive subject, but I would suggest a ‘mega flush’ of the gearbox where that flushes out 90-95% of the oil. Some like them some don’t. I had mine done the first year I bought her then had a filter change the following year, belt & braces in my mind. Bodsy on here is re known for his workmanship & will come to you I believe, even ‘op norf’.😜

Ah right thanks for all the replies I did not consider the gearbox I thought it was more of a power issue

A modest investment in a GAP IID diagnostic tool will save you £££ and lots of time. 2012 TDV8 Vogue (L322) |
