Engine Carbon Clean Nissan Qashqai

Here we have a Nissan Qashqai+2 1.5 dci (2009 – 174,870 miles) booked in for diagnostics and Engine Carbon Clean after the owner had noticed performance dropping off, getting progressively noisier and also some puffs of smoke. Having owned it for over a year it had always had a noisy vibration from the front left.

Initial inspection found quite a significant vibration coming from the intake system so we investigated further. The air filter was very dirty indeed and whilst we performed the clean the owner quickly popped out to get a replacement. With the new filter in place the vibration lessened, but was still quite loud. Closer inspection found what looked like a repair to the intake system at some point in the past. The owner suggested he would take the headlight out after we had finished and look to see where the problem was. Given the state of the air filter it was likely that there was a disconnected or broken plastic pipe, just not what we could immediately access.

Initial diagnostics showed some old codes for the key and fuel pressure, but current codes relating to the glowplug relay/controller.

Live data monitoring showed all temperatures where they should be and DPF had last regenerated 41 miles previously.

‍On with the Nissan Qashqai carbon clean and intake system aside the vehicle soon quietened down, smoothed out and the throttle response returned.

❗ The owner contacted us later to say that once dismantled and reassembled the intake pipework no longer rattled…

‘Hey Adrian, I managed to clean out the intake it was very dirty the humming noise has totally gone after reassembling the air box. My wife says the car feels more responsive and the engine is definitely quieter. If she is happy the I’m happy, Many thanks’

I had a DPF clean which has worked perfectly and got my diesel Rav4 back into perfect driving condition. Steve, the technician was very friendly and talked me through the whole diagnosis and treatment.

Just had my car done by F5ECC. Adrian talked me though how the process works. This is the second Merc I have had done by him in 2020. C250cdi and now a C350e sport. Noticed straight away more mpg. The car felt a lot smoother on acceleration. I was quite shocked at how much quicker and responsive the car was when I put it in sport+. I highly recomend having this done.

Adrian came out and did a carbon clean on my Mercedes CLA45. If you've purchased a used car that's done a good amount of miles then I would highly recommend getting this done. It made all the difference to mine. Throttle response is better the car feels better as it climbs through the gears. Adrian was here for about an hour, was happy to talk through the process and shared diagnostic info straight to my phone. Really helpful and knowledgeable. Owen Moore.

I found this organisation on Google. It had great reviews and the service which I required which was a carbon clean. I found Adrian very helpful and knowledgeable. While he was carrying out the service he explained everything to me and how it works. The car feels better now with it being more responsive and quieter. I would recommend Adrian and his company to friends and family if they required his services. Thanks Adrian hopefully see you again sometime.

This was my first experience with F5 carbon and DPF clean. I was a little desperate as I had been let down twice by a larger franchise company. Mark the technician managed to fit me in at short notice, what a stroke of luck for me I found Mark to be an extremely knowledgeable and professional guy. After running the diagnostic and clearing a few issues he managed to get my DPF working properly and able to do the regeneration process on its own so only charged for the diagnostic even though I had booked for a full DPF cleaning. I cannot recommend F5 enough it's a real pleasure to deal with them. All round excellent service. Thank you guys.

Adrian is a lovely fella, explained the process, carried it out well, clearly done exactly what it needed to do as I blew a load of stuff out the back when I drove it after. Will definitely be coming back in the future.

Steve arrived to give my Jaguar xfs an engine carbon clean. Presently on 107,000 miles. Explained the process and was obviously very knowledgeable about the process and expected outcomes. And he was a thoroughly nice chap. The V6 in the xfs is a quiet, smooth, powerful unit and I was not sure of what improvements I would get. Well, I’m impressed. The power delivery is smoother, the engine even quieter and 6 mpg better to boot. If you want to do one thing to maintain and improve your motor, then this is what you should do.
