Combustion gas in the coolant? I assume the green is the contaminated and blue is what it should be if no CO2 present?

200k is fairly decent for that engine or indeed most engines , few get much further these days
It sounded very rough in your little video so I didn't think it would end well.

You know I got a snicking suspension the engine was patched up when I bought it.
I've had that car maybe 8 years!
It had 199k on the clock. Cost me about 900 bucks.

Just as a chaser oil 10w30 Walmart brand.
Left the oil filter cap off.
Now I'm rewarded with cleaning up!

Well ordered the ancel bm5000 this scanner has the relearning capabilities for the bmw throttle body.
Resulting in a smooth engine idel and responsive gas pedal... should receive it in couple of days fingers crossed

The horrible rough idel I'm experiencing all due to a dead unresponsive throttle body.
For this model year I must use oem!
I'm told that the ecu is highly sensitive and will accept vdo only!
Anyone here have this experience...Thanks!

I don't know about the petrol models but a cheap throttle body I bought for my x5 35d didn't work correctly , the car ran ok but wouldn't regen the dpf.I had to buy an oe pierburg in the end .
Accurate
