Thread: What happened to your D3/D4 today?

I’ve been running the “extra 10” HPR stuff too for a while. I have nothing empirical to add as I don’t oil test but it hasn’t destroyed my engine, yet.

Same, though I didn’t know until recently - the 40 weight is used by my indie…

Finally got my TDV6 out of "Reduced Performance Mode" and the engine light extinguished today. I am presuming my actions cleaning other components during replacement of the oil cooler had created the problem, namely the MAP sensor which was totally clogged with congealed grease.

What I cannot come to terms with is how this component can throw DFCs regarding the Oxygen Sensor, MAF and the Glow Plugs. PO 380. PO 0030. PO 010C.

These faults were indicative of shorts to ground which voltage and resistance measurements could not identify.

My purchase of a iCarsoft Vs 2 Diagnostic Tool cleared all these codes. A multimeter had confirmed that the MAP had no voltage output despite the 5V supply being present.

Whilst throwing parts at the problem I also replaced one of the MAF sensors which had a questionable output voltage.

The Indie Repairer has missed out on a Xmas bonus at this point in time, I hope my good fortune continues.

Something weird happened yesterday. I was driving at 60km/h and I was wondering what happens if you lower the car. So I press the access height button and it seemed happy to lower. Obviously I don’t know if it actually lowered or not as I was driving. Maybe a minute or 3 later it put itself back into standard ride height. It wouldn’t go into off road height while at 60.

I don’t have a scan tool

Sounds normal to me.

From the WSM...

Access mode lowers the vehicle body height by 50 mm (2 in) and provides easier entry, exit and loading of the vehicle. Access
mode can be pre-selected when the vehicle is moving. The vehicle will partly lower as the vehicle speed decreases, lowering to
the full access mode height when the vehicle reaches 5 mph (8 km/h). If the required road speed is not reached within a
predetermined time, the air suspension will return the vehicle to the previously selected height.
Access mode can be selected at any vehicle speed. When access mode is selected, the response of the air suspension system will
depend on the vehicle speed:
If the vehicle speed is more than 12.5 mph (20 km/h), the air suspension control module will wait for up to one minute for
the vehicle speed to be reduced. The access mode lamp and the lowering lamp will flash while the air suspension control
module waits for the vehicle speed to be reduced, the on-road mode lamp will remain illuminated. If the vehicle speed is
not reduced sufficiently, the access mode request will be cancelled after 1 minute.
If the vehicle speed is less than 12.5 mph (20 km/h), the air suspension control module will lower the suspension to a part
lowered height and will remain at this height for up to one minute. The on-road mode lamp will extinguish as the air
suspension control module lowers the suspension to the part lowered height. The access mode lamp and the lowering lamp
will illuminate. When part lowered is reached, the 'lower' lower lamp will flash. If the vehicle speed is not reduced to less
than 5 mph (8 km/h) in the one minute period, the access mode request will be cancelled.
If the vehicle speed is less than 5 mph (8 km/h), the suspension will be lowered to access mode immediately. The access
mode lamp and the lowering lamp will illuminate. When the access mode height is reached, the lowering lamp will be
extinguished.

What Graeme has posted above.

Off road height is not available above approximately 40Km/hr.
