Webasto HL18 manuals added to reference pages

Not entirely Sprinter related but again I’ve fitted one of these diesel air heaters to our van (kindly donated by a friend) so I’ve added the manuals including the service manual online here. it’s a great air heater for the money, reliable and easy to service.

Ours is currently mounted to the top of one of the rear wheel arches with the exhausts emerging in the when arch at the rear of the vehicle.

EDC light, no power and a quick fix!

So there we were today driving home in our Sprinter when the EDC light came on, we had a blip/cough and then loss power. Engine would restart and then simply die if you touched the throttle.

I managed to coax her into a lay by and safely park up.

Thankfully I was carrying our handy MaxiDiag Elite diagnostic unit (buy one if you don’t have one) which showed up a series of “excess current on common cable” errors on the injectors.

I had read about this error before and have heard of the engine loom chaffing on the mount points. Sure enough, a quick check of the loom running to the top of the block showed up a suspicious mount just to the left of the battery and underneath the loom had worn through and was touching the mount.

With this taped up with some PVC tape and then secured with a zip tie to prevent further chaffing the problem and error codes were instantly gone and we made our way home. If you fancy some preventative maintenance I highly recommend cutting the factory zip ties on these areas where the harness is attached to metal brackets, padding them with some cut down rubber strip then reattaching the cable with some new zip ties.

So from this we learnt, know your engine, read and absorb the content on Sprinter Source and always carry tools and a decent diagnostic tool!

Carver Cascade 2 initial bench test

Well good news, the water heater gas system and auto igniter works just fine. Bad news, the boiler has rusted on the left side resulting in a gas leak at the end of the boiler which results in a flame where there shouldn’t be one.

Boilers (the rectangular stainless part with the gas jets in it) are around £50 and standard off the self spare parts. The entire brains of the system can be removed from the roadside and the boiler replaced easily.

The rust problem is due to heat, the proximity of water and exposure to the elements as this all faces the roadside. I am going to try a repair initially as the boiler box is not under any pressure, just heat. If the patch I am going to try with some exhaust epoxy and spare metal sheet doesn’t work I’ll bite the bullet and buy a new one.

The water tank needs to be pressure tested, the wax thermostat that acts as a safety preventing overheat also needs testing and then she needs a clean up and can be installed into the van side ready for the pipework.

Installing a Carver Cascade water heater

I’ve hauled a Carver Cascade 2 water heater out from our donor caravan for our campervan build. These combination gas/mains water heaters have been common place in caravans for years and little has changed. Parts are pretty easy to obtain and the unit can be services and maintain. There’s a handy service guide for them on Practical Caravan.

Ours is in pretty good nick having examined it today; that said it will need to be test run on the bench outside first, then cleaned up before install. I see no sense in cutting a square out of the side of the van only to find I need to rework the install!

I found a handy resource for anyone looking to use a Carver Cascade heater online at Arc Systems. I’ve replicated the documents on the resource pages for anyone else that wants them and will add anything else that I find that’s relevant.

Shower install ideas

I have been plotting how to best install our toilet when I came across this video when I went down the rabbit hole that is YouTube…

I now have a new subscription for me to keep an eye on, cheers Jaz.

Best Sprinter accessory? Why a motorbike of course!

When you absolutely, positively have to have spare wheels with you; what’s better than a motorbike? Next up will no doubt be a bike tow/loft hitch for the back.


I needed a commuter I could park in the city and ended up buying a second hand BMW F650GS Dakar. Good news is that it is a great bike and gets me 70mpg on an average day, bad news is that it has distracted me from work on the van and updates here. For one I have a parasitic load on the starter that I need to cure, I am pretty sure that it’s coming from the split charge circuit having replaced the alternator regulator.

I may well add a few posts on here covering BMW single cylinder maintenance issues that I come across. Obviously she needed a service and a few repairs to make her suitable for the road, a clean up and some parts bolting on.

In the meantime here is a great website from a couple travelling around the world on their BMW F650GS: https://lifewelove.com/en/

Now I find a commute on my 650 comfy, but it’s a different league hauling all your kit and partner on the back too!

Build blogs: another random van conversion I’ve found

I thought I ought to keep note of the random blogs I’ve found covering individual van conversions, including this one called The Human Portrait Project. Why list it here? Well I might forget the link otherwise!

I was interested to see the build comments they made, specifically about silencing the interior of the vehicle and also rustproofing the outside with Rhino Liner; two things that I am planning on doing myself in very similar way for our vehicle.


Cleaning up the front axle area, waxoyl

In an effort to keep the inevitable Mercedes rust away I’ve been working my way around the van dealing with rust and preventing it where I can prior to respraying the bodywork.

A combination of a wire brush collection, Jelonite rust converter, Waxoy, Hammerite spray paint and a few other products have been used to clean up the areas around the drivetrain and also respraying our steel wheels black. Taking on a family member’s advice I’ve treated the brake lines with Waxoyl from front to back, especially around the supporting brackets. The exterior areas of the brake callipers have also had a quick coat of rust converter and paint as they were looking terrible.


T1N or 2005 Sprinter alternator – regulator replacement

It turns out that regardless of what rated ampage your alternator is if you have a Bosch BR14-M3 alternator fitted then they all take the same regulator.

Common reasons to replace the regulator are if the brushed are worn down or (like ours) if the diodes begin to breakdown and you either get voltage issues or a current leak causing a flat battery when parked up.

The Bosch part number for the new regulator is F00M144139 which supersedes  F00M145248 which is what I had fitted. This regulator is suitable for 90/120/200A units.

Bosch won’t release or send out spec sheets but details can be confirmed with them direct, just speak to their automotive technical department:
