Impressive!

DF010 with the message "Memory, PUMP MOTOR CIRCUIT - Incorrect supply voltage or short circuit"... I would be tempted to check the wiring first, which means tracing the wires on the circuit diagram, and if possible checking for short circuits or broken connections at the ECU side of the loom. I have ...

Never clump flexi hose. Just open the reservoir under the bonnet and wind back the piston. Usually it is easy, but if seized, then order a new caliper.

I was replcing the break hoses a few years ago with those teflon ones covered with stainless steel pleating, and in order to prevent fluid loss ...

I mostly use Purflux, Mahle and Mann-Filter brands in about this order, while keeping Bosch as a reduced performance but still reasonable option.
Note, Purflux is OEM for Renault.
Note, Purflux makes "chevron pleated" oil filters that have about 25% more filter material than the matching Mahle and ...

Good cabin filters:

MANN-FILTER CUK 26 005
MAHLE LAO 684
Purflux AHA281

Fine filtration, activated carbon, antibacterial and antifungal.

Update 2026:
Purflux AHH281 seems to be the best at the moment, finer filtration to HEPA standards, more filter media for better airflow.

Apparently, it is very easy to disable the tyre pressure monitoring system in the ABS computer. Use ECU Tweak tool for Android and ELM327 for it, as in my other thread.

Revisiting many years after...

When changing the rim/tyre size it is possible to bias the readings of the speedometer. This can be corrected by updating the configuration of the ABS computer with Clip or a free tool ECU Tweak , see my other thread about free software tools and EM327 interface ...

I've been using these for a while, decided to share...
Clip diagnostic computer is expensive, but this days one can get similar functionality with free programs for Android (or other computers) and a cheap interface unit based on ELM327.

For Android one needs an OBD box having either Bluetooth or ...

I meant that there can be corrosion damage to the UPC if the wheel arch liner let's spray in. This is easy - either fix the visible damage or replace the block. This is what garages usually do.

If it is OK, then significant expertise will be needed to check the functions of the individual signals ...

This part looks like a clutch damper (sometimes called clutch resonator, perhaps due to imperfect translation from French), but in the workshop manual it's called "piping with filter" (unclear whether they meant a sediment filter or vibration filter). The damper's only purpose is to reduce ...

The Truth is born. Best wishes to all!

My guess is that the buzzing noise is either solenoids or the stepper motor on the throttle. When the ECU is unsure about throttle position, it attempts to close it. A problem with the battery voltage may trigger such a behaviour. Some electrical buzzing is usually heard under the bonnet just before ...

The next time this happens check the voltage of the battery. It may be loosing charge overnight, but then quickly charges once the engine has started. Check, clean and protect with silicone or other grease the terminals and any associated contacts. I think the problem is somewhere around the battery.

The driver's door was clicking loudly. Upon some research I found that this is often caused by the retainer shifting up or down in its rollers. So, looked into mine - it was in the low position. Apart from this, everything looked good.

I found a cheap solution not involving taking off the door ...
