Mistermena

I haven't had any problems since those few days. The car is driven at least 60 miles every day so it wasn't as if the car had been sitting idle for a while. Very strange!

Mistermena, thanks for the advice. Just under 50k on the clock at this stage. Not sure when the gearbox oil should be replaced but i'll do it anyway. One of the few relatively cheap and easy jobs to do! Can't say the same about a synchro though!

Reganlives, I have a service due in the next couple of weeks so i will be enquiring then.

Well I've changed the box oil on my car. I used Silkolene Pro SRG 75 (Full-synthetic ester racing gear oil) and what a difference it made. No more problems when changing gear when cold, and no crunches when going into 2nd anymore. Well worth the money from the guys at Opie Oils.

hi all!

for my 4 year old 70k miles is250 auto i used bg44k i bought from www.powerenhancer.co.uk. my car use to shake when i stopped at junctions and on one occasion it stalled,i did a bit of research on the american side and found they use this stuff at lexus,audi,vw dealers. after each service the dealers put can of bg44k for petrol or bg244 for diesel in to petrol tank. i used about 3 weeks ago and found the engine was smoother and more responsive and no more flat spots, it does not shake anymore,the revs use to drop to 400 and back up to 700 when stop, does not do it anymore. i tried bg244 on my dads bmw525d with the same results.i am getting between 3-4 miles more per gallon than before with same style of driving.i have had the car since new and the engine now feels like new.hope this information is of some use to you guys that have still got problems with carbon build up.

I've just ordered some now! Hope I get the same kind of results B)

From where and how much?

Have you tried this yet?

Its great stuff! I ordered mine from www.powerenhancer.co.uk when it was on a special just after Christmas. But I didn't do what it recommended on their web site as I was unaware of the time scale that you should try and keep it in your tank for.

I was away for the holidays and put the bottle in thinking that the long 4 hour drive home would be the best time to use it! But I realized now that the way to use it is by trying to keep it in the tank for at least a week and driving short trips. After which you add more derv when about a quarter of the tank is left. So I've bought some more to do just that.

One thing I did notice was the smell from the exhaust! Like a burning smell, but not that strong. I'm guessing it must be the BG244 getting rid of the carbon and soot build up in the DPF...

Hi All,

Any help would be greatly appreciated. I drive a 07 220D.

I had to drop the folks to the airport very early in the morning one day last week. First hard frost of the year so may be a factor(???).

Went through 1st to 3rd no problem, then tried to move into 4th, but the gear would not engage. No grinding though. Went back down through the gears even skipping to 5th but still no luck when trying 4th.

Five minutes into the journey 4th finally selected but with a typical grinding noise for a brief moment as it slipped in. This continued each time I tried 4th, as I said it would select but there was the grinding noise briefly each time. 10 minutes later and since then there has not been an issue.

I haven't heard of anything like this before, particularly applying to one specific gear, but I am not a mechanic!

The car was serviced just over two months ago (4000 miles ago).

Thanks in advance.

Sounds like it could be the syncro going on 4thn gear! Have you had the gearbox oil changed? I'm going to do mine when the weather gets a bit better. Hope this helps...
