There are likely to be different regulations depending on the country you are living in. As for tinted windows - they have to be within a certain allowable range for the front windows, but the rear windows can be darker.

In the UK for vehicles from 1st April 1985 or later, the front windscreen must let at least 75% of light through and the front side windows must let at least 70% of light through. We don't have any fitting certification, but the front windows must be legally compliant. It is not part of our MOT test, as there are only a small number of vehicles affected and it would be too expensive for testing stations (in excess of 18,000) to buy this equipment just for this test.

As for towing bars - I can get you the proper recommended Citroen approved towing bar and harness part numbers if you want. There are aftermarket versions available - but these will differ according to feature and function. The proper Citroen ones will incorporate a trailer unit ECU and interact with the car's ESP system (if fitted) to apply a proper ESP programme when towing. So down to choice and budget. As for fitting - it has to be properly fitted as it is also part of our MOT test.

Same goes for fricking towing bar. For window tint I will just "modify" one from the internet or something, but what do you guys sugfest about towing bar? I have no clue where to get certificate for that. I have no clue what brand or anything is with that. All I know is, it is for C5 2001-2004 and that it is "hidden". You cant see it unless you get down on your knees and look under the car. Suggestions needed guys :)


This must be some 'paper-work' which is only required in your country. Here in the UK you only need to use a towbar which the maker has submitted for approval. So in fact any towbar which you buy from a reputable supplier will have approval. After fitting it, you need to tell your insurer since your car has been modified.

But no certification needed, which is his problem.

Yes, just following on from the last paragraph referring to UK.

@ DoomsDay - I would buy it yourself and just get an approved fitter to do it for you if that is what you have to do over in your Country.

Thanks for all the feedback. Last time I was replying from my phone so I didnt told everything about the matter :)

Yes, we also have that 75% for windscreen and 70 for front 2 sides. Everything else is 55 or even less. That is the reason, that I tinted only back passangers and back windows, so that noone would be "dramatic" if it is 69% or 71% if you know what I mean :D However, besides that (we have a few of this machines, that can measure how much % window is tinted and they also do it when you take it there) our country is so "great", that you also need a "prorfesional" to do the tint job. And "profesional" can be only a person, that has car stuff bussiness AND even he needs to get a "approval" from government that he really is profesional. (he pays for it) So after he tints your windows, he gives you his certificate that states his job is done corectly and "safe" (costs $$$) and he used XXXX tint foil that is approved from governement as "safe" and stuff... complete bollocks :D So, I will sadly have to get my "unprofesional" tint down and take it to a shop if I want tint to be installed. (if police stops me now, I get a fine of 400€ so **** that :)

About towing. I got the original for C5 MK1, problem is, that I found it on a scrapeyard basically, it fits like a glove, but because it was so old and rusty when i found it, I have 0 clue what model it is. If I found out the model that is, I can get certificate for it. Any ideas? I can post pic of towing bar if it helps.

Any1 knows how can I tell if my car fuel injector is Bosch or Siemens? Is there an easy way to tell? Can I do it with VIN number somehow? I found just one topic about it, where they said, that I need to check near ECU under the hood if there is anything written. If there is, it is Bosch, otherwise it is Siemens. Kinda lost...

Best regards,
Doom

If you have an electric pump low pressure pump in the tank, it's Bosch. If you have a squeezable hand pump under the bonnet then it's Siemens. At least that's the way I was told.

Not the best way I'm afraid, I happen to have the Delphi system... and then there are the differences between those systems depending on variation of engine / emissions etc.

Ok, so you have the DW10ATED TURBO DIESEL 110 WITHOUT FAP.
You also have the Bosch injection system on your vehicle.

Were Delphi systems fitted to the Mk1? I thought it was only Siemens and Bosch. And that Siemens was fitted to the 90 bhp version and Bosch to the 110 bhp. Or is that taking it too far?

Although Siemens and Bosch were certainly the main Injection ECUs for the time Paul, there were significant variations within those units for the different engines and options.
