Engine fault: repair needed – the oxygen sensor & bad fuel

A lot of work for nothing

When your RCZ error message shows “Engine fault: repair needed”, many things can be at the heart of the issue. If you’ve watched the first episode of this saga, you know what I’ve already tried to fix the issue. As usual for modern cars, it’s always best to get a readout of the problem by connecting the car to an OBD2 diagnostic tool. But what if the read out of that tool is not accurate enough and you end up changing something like, let’s say the oxygen sensor and it turns out that that’s not even the problem? Darn… So now what? Find out in the following video. πŸ™‚

 

Engine fault: repair needed – the recirculation valve

The long search for the fault

Sometimes when you think everything is fine with your RCZ and you’re driving along not looking for any trouble, that’s when it hits you – an error message comes up the display..! More specifically “Engine fault: repair needed”. In case this happens to your RCZ or Peugeot in general or CitroΓ«n or even to your luxurious DS, it can mean many things – it’s basically a very general fault code for your engine. However, it doesn’t always mean that the fault origin is to be found in the engine. Find out one example in the following video! πŸ™‚

Setting up the android autoradio

Personalization is king

If you read the previous article and watched the clip, you might be missing something. Exactly, it’s one thing to know how to install an aftermarket android color screen autoradio to a Peugeot RCZ and another one to set it up. From startup logo to reverse camera, there is a gazillion settings you can personalize to your liking. What else? Click on this video and find out! πŸ™‚

 

Installing an android color screen autoradio – Peugeot RCZ

Catapulting the RCZ into the 21st century

The RCZ is a well built and styling little GT car. The kind of style that has a real potential to become a classic collector’s item in a few years, just like the 504 Cabriolet and the 406 CoupΓ©. However, when you look at the dashboard, there’s just one thing that makes it look quite dated today, even when it came out in 2010: The center control unit. Just look for yourself:

Clearly, some cars are best kept original and some just need ‘a little help’. How about keeping the original style but adding some of the modern day gadgets like a color screen and android technology with all the apps you can have on a smartphone. Speaking of which, this opens a gate to whole new world! What world? Find out by watching the below video. πŸ™‚

Transmission oil change – Peugeot RCZ

Shifting gears smoothly again

Everyone willing to maintain their car will either have it serviced by a technician or maybe even service it themselves. A general service includes checking the overall functionalities and state of the car, as well as changing the engine oil, oil filter, spark plugs, air filter, maybe a fuel filter and occasionally and every four to five years, the coolant. But what about the gearbox / transmission? Most cars this days don’t even have a gearbox oil dipstick. Most manufacturers these days call them “sealed gearboxes with lifetime oil”… Right, the engine oil is supposed to be changed regularely but the gearbox oil will last forever? Nice fairy tale!

I changed the gearbox oil of my RCZ at around 90’000 km and trust me, it was worth it. I’ll probably do it again every 60’000 km. But how does it work? It’s actually quite simple. Watch the below video and see for yourself! πŸ™‚

Bleeding the brakes – Peugeot RCZ

Brake fluid 101

What makes good brakes? Sure, you have all the mechanical components like the master cylinder, the brake rotor, caliper, pads and so one. However, none of that would ever really run properly if it wasn’t for the brake fluid. The brake fluid is used to transfer the brake force you apply on the pedal into pressure on the brake pads that eventually push against the rotor and through friction slow the wheel down.

Even though the brake fluid circuit is closed, there are several occasions which require it to be changed or at least topped up. For example, when installing new brake pads or a complete new set of brakes or simply when the fluid has gone past its expiration date. As a matter of fact, brake fluids are hygroscopic (water absorbing), which means they absorb moisture from the atmosphere under normal humidity levels. The RCZ such as many other passenger cars uses DOT 4 brake fluid, which is supposed to be changed every two years.

Changing the spark splugs – Yamaha XVS 1100 Drag Star

It’s electrifying

After changing the air filter, the next step would be to put new spark plugs in this ride. Spark plugs are usually changed once the respective mileage prescribed by the manufacturer is over. On my Drag Star, I change them every 10’000 km. I use the original NGK BPR7ES units. The procedure is pretty straightforward.

Here’s how to do it! πŸ™‚

Installing a FOX sports exhaust – Peugeot RCZ

The first really significant modification to my RCZ

Enough of the routine maintenance, let’s get some excitement into this ride. The K&N air filter was a good start, but why not upgrade the RCZ esthetically while also improving the sound note?! I decided to install a FOX dual exhaust for three reasons: It looks great – chrome, classy and bigger than the stock exhaust – hopefully sounds great and it’s road legal in Switzerland. Furthermore, I went all in and also acquired a matching sporty rear diffusor that allows the new right side exhaust to come out.

NOTICE: The installation is quite straightforward. As always, take some time to prepare yourself and don’t rush the whole disassembling an reassembling. The kit was complete. You don’t need to cut or weld anything to the chassis. However, you need to cut the stock exhaust pipe at the exact spot, in order for the new pipe to fit. More tips are given at the end of part 2.

Here’s how it’s done! πŸ™‚

Part 1 – Removing the original exhaust and prefitting the FOX exhaust

Part 2 – Final assembly, sound check and feedback

Resetting the service warning message – Peugeot RCZ

Keep your computer up to date!

So you’re one of those people who service and tune up your car yourself, right? But what about all the electronic little messages that come up periodically and want to remind you to look after your car? Of course, YOU wouldn’t need that because YOU keep track of your car’s maintenance history, right? Well guess what, you still need to tell you car when you changed the oil. My RCZ‘s onboard computer wants me to service my car every 30’000 km. It shows so buy putting up a little wrench next to the odometer, as well as in the central display between the rpm gauge and the speedometer.

Lucky you, you drive a Peugeot and hence don’t need any diagnostic computer to reset the service warning message!

Here’s how to do it! πŸ™‚
