Ahhhh ok so I have read about ChippedUK on here - are they the best place? I have also seen the decats on a Scotland based website/company - are these the best? Finally, how do you bypass the EGR? I have done it on previous cars by simply blocking the openings on inlet and exhaust.

What's the best route for remapping the 525D? Has anyone used a DTUK tuning box? Thanks

As above, running E34 520i at the moment but getting a bit bored with old interior. Considering an E39, are these diesels easy/cheap to tune? Are they reliable? Are they economical? Thanks guys

Is it accessible without removing interior trim?

My steering feels rather slack when my cars stationary on the spot. Someone told me there is adjustment in the steering box that can eliminate this slack. Is that true and if yes, how is it done? Thanks

Ok I think new clips are in order. Just out of interest, does anyone know which pipe is the return pipe from the pump or box? I can see one goes to the pump and one to the box, but which way does the fluid flow?

Well ever since I bought the car six thousand miles ago, it's always leaked. However, it's not really an issue because it simply empties the reservoir but the system itself remains full, so, not a big deal, but while I was on the case I thought I would fix it. Now that the genuine seal doesn't work properly, I may just silicon the bottle back in. I know it's a bodge, but if it works, then that's an improvement.

Exactly, so the genuine BMW seal doesn't really fit snug in the lower recess on the genuine BMW bottle... Typical, just my luck, I'm sick of this cheap rubbish now really, out comes the silicon sealant.....

Have only tried fitting with seal in lower slot, feels as though it goes in tight but still seeps from the gap slightly.

Me too, but the old one was in the lower recess... Unless it popped down into the lower recess from the upper as I removed the bottle?

Which recess does the coolant reservoir seal go in? Upper: Lower: I originally fitted it in the lower recess, but it's not a tight fit so i thought maybe it's meant to go in the upper recess??? Ed

How would I get a recon E34 pump or get mine done?

I know you all know how to bleed an E34 but I've been told so many methods I just thought I'd share one that I know works.

I don't really seem to have any issues bleeding mine! I'll share my method: 1. Reconnect all pipes/hoses and secure all clips. 2. Remove reservoir cap and bleed nipple. 3. Switch key to ignition '2' and heaters to hot with blowers on max. 4. Begin to fill reservoir with coolant slowly until coolant/air bubbles appear from bleed hole. 5. Replace reservoir cap and bleed nipple. 6. Start engine and run with heaters on full blast until temp needle is at 12 o'clock. By this point, the heaters should be running hot or at least getting there. 7. With engine running, crack open bleed nipple and release air bubbles. Close bleed nipple. 8. Switch engine off. Allow to cool fully. Top up coolant. 9. Fire up engine, bring to operating temperature with heaters on full blast etc, crack open bleed nipple. By this point, mine is fully bled. I'm running a genuine BMW housing with a BMW seal. The thermostat is from GSF. I know everyone's car is different but I honestly don't have any issues bleeding.

I'll check but I think they're crimped.
