Some of the pieces went into the cam belt. The vehicle came to an immediate stop. We opened what we could. We had assistance from a few bush mechanics – guys who are famous for fixing everything almost everywhere. No success was achieved this time. It seemed as though the problem was a little bigger than just replacing the belt and resetting the timing.
I phoned Bohdan de Wet in South Africa. He is Mr. Fixit for Volkswagen SA. He said he would fly up immediately to attend to the problem.
When Volkswagen made the offer to supply vehicles for this year’s expedition, it came with an additional offer: If you run into technical problems, we’ll send Bohdan to fix them.
The Amarok is a new vehicle. Thorough testing may have resolved most issues regarding reliability, but there is the odd chance that something unforeseen may happen, especially as we had fitted some aftermarket equipment, such as bull bars and suspension. This may have an unforeseen effect on the performance and reliability of the vehicle.
Bohdan asked us to get the vehicle to Nanyuki. This was a major undertaking. We managed, with the assistance of a Kenya Wildlife truck and its driver, who was prepared to drive for 30 hours non-stop.
We left Sibilio National Park just after one in the afternoon. At first it was a desert track, similar to those in Damaraland. By sunset we were approaching North Horr. The locals advised us not to proceed. No vehicles had reached this town in the past few days because of the torrential rain in the desert. We turned down their advice and pushed on.
The Track4Africa tracks were good. But roads and tracks change in the desert because of seasonal conditions. At times we found ourselves on totally different tracks to those on the GPS. We crossed dry sections of higher ground. Then, every so often, it was down to a “dry” riverbed. These riverbeds had become stretches of mud. We had to tackle the terrain with a fair amount of momentum, in low range.
Do I have any doubts about the 4×4 ability of the Amarok? Not after that journey through the desert, one night in November, 2011. These vehicles were developed to tackle serious terrain.
We arrived in Nanyuki at the same time as Bohdan flew in from SA with a new head for the two-litre engine. He had his suspicions about what had gone wrong.
Bohdan examined the problem. Further investigation will probably prove his theory, but at this stage it looks as though the problem originated with the bull bar, which has fins that might have directed dust and small pebbles onto the belt. This caused the belt to eventually tear, and pieces of the belt went into the cambelt. This had a major effect on the engine itself – the valves were burnt.
Bohdan had brought a complete new head for the engine. Within a day he had everything replaced, and we could continue our journey.
These are the kind of problems we believe are being sorted by VW as part of their learning curve in this demanding market. Perhaps a small adjustment to the ARB bull bar is all that is needed. Or a minor adjustment to the cambelt cover design.
In any case, to rectify the problem so that it doesn’t happen again seems a small matter in the overall scheme of things, but it had a major effect on us. We were fortunate to have Volkswagen Commercial Vehicles standing up to their promise to assist us with anything, anywhere in Africa.
So, sure, there may be a few issues relating to specific applications — reliability, for one. But with Volkswagen, one believes they will be addressed."
Please bear in mind that this is written by one of the adventurers, and he has a vested interest in not upsetting sponsors, so I think he couldn't say what he REALLY thought............
