Fault Code Reader - worthwhile investment for me?

On startup, my car (details in sig) does its system check and then reports SERVICE in orange. When I bought it, I just assumed that it was telling me it was overdue for a routine service. D'UH!

Now I understand that it means the car has detected a non-fatal fault somewhere and I need to go to a Renault to check it out. Yuk, that's the costly option, I think.

Halfords quoted me 49 to do a one-off diagnostic check. But now I've seen that I could buy my own car fault code reader (e.g. 2016 Universal Car Fault Code Reader D900 OBD2 EOBD CAN Diagnostic Scanner Tool | eBay )for far less than that, and use it multiple times on multiple vehicles. Seems a no-brainer, as far as I can see.

My issue is that some reading around tells me that some/many of these readers struggle with diesel engines before 2004. My car is 2004, although obviously the engine was developed a few years before then.

Then there are various types - OBD, OBD2, EOBD, EOBD2, and possibly others. That's Double-Dutch to me, so could someone tell me what the differences are?

Which type is good for my car? I only want something basic, just so I can understand what the car thinks is wrong with it. A blown bulb or a potential engine failure? I'd really like to know!

Have you checked, does it need a service,, windscreen wiper stalk, press the tip , scroll through, different things will appear..
Does the one you have linked to, cover your Laguna

I remember the first time I saw a universal remote control, and I thought to myself.

Re: Fault Code Reader - worthwhile investment for me?

Modern cars can be a nightmare without a reader.
Would always have one in my toolkit.
But a reader is not a substitute for thinking and generic can lead you astray as codes are generic and may not accurately define the problem.

Basics
OBD and OBD2 are the worldwide standards, OBD2 the latest.
EOBD(2) are the European equivalents and the protocol that Euro cars are produced to.
To all intents and purposes for the average DIY, the same.

The protocols only cover engine faults, ie what is in the ECU .
So forget airbags or bulbs and the like, not included.

Cheap readers will only cover the ECU and OBD protocols, more expensive will get you deeper into the car and into specifics for the make.
Pays your money, takes your choice. Professionals will almost certainly invest heavily into top range all singing and dancing.
DIY...cheap as chips do the same as more expensive OBD2 readers but are more likely to be clones that may not work, pays your money takes your pick.

Stick ELM327 into ebay , hundreds of the things.
The wifi and Bluetooth ones will happily connect to your mobile (smart) phone and turn that into a usable scanner.
With decent App, Torque on android, can get real time readouts that may help with what is happening as well as error codes.
Couple of quid from Hong Kong, fiver from UK... do a job.
Wifi enabled gets you into IOS and Android and less likely to be a cheap clone... if you can find a true V1.5 (don't trust the advert wording) can get into one app that is specifically for Renault and gets into other controls then the ECU .

Caveat Emptor but as good a starting point as any.

Whether they will get into your diseasal ??
While protocol only became mandatory for diesels after 2004, never an issue getting codes from my Scenic (54 plate) and though cannot get codes from my Kia (2002) can get some live readings.

well said DD its been a mine field for years and bet there are 1000's of diagnostic testers just sitting in a garage/shed that didn't work on said cars so will never see the light of day again

Thank you for taking the trouble to give a succinct but detailed answer. The first learning point I've gleaned is that there's no point at all in me buying a cheap hand-held scanner, because an ELM327 thingie linked to a standard phone or laptop will be cheaper and do a much better job.

I'm fine with that. I can use basic common sense for much of the non- ECU stuff, I think (hope).

I'm currently down to two from which to choose - both look like they're from the same UK-based seller. One uses Bluetooth and the description from the seller says "The bluetooth module is always the cheapest one available and gives limited range and stability"; the other uses wifi and the description says "The WIFI module is always the cheapest one available and gives limited range and stability". My head hurts trying to understand these boys.

In your experience, is Bluetooth or wifi more reliable, convenient, etc.? I'll probably want to connect to my old Android phone most (via Torque Lite to begin with), but it would be nice to have the option of the unit being able to connect to my iPhone (via dashcommander, most likely) in the future.

This comment has left me a bit puzzled, I'm afraid. I looked up the wiki page for ELM327 and it suggests in the section about pirate clones that there's no such thing as a "true v1.5". It says "Released software versions for the ELM327 are 1.0, 1.3a, 1.4b and 2.1 only. .... Most of the clones are reporting ELM327 v1.5, despite the fact that Elm Electronics does not have a version 1.5."
