--- title: Tyntetown: AdBlue in a Diesel Tank, What Next canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/tyntetown-rhondda-cynon-taf/ location: Tyntetown county: Rhondda Cynon Taf latitude: 51.661410 longitude: -3.350800 service: AdBlue in a Diesel Tank updated: 2026-10-15 --- # AdBlue in the Diesel Tank in Tyntetown: What Now? All of it hinges on one fact: if your motor has started since the AdBlue went in — far more than anything else. If it hasn't, keep it that way, whether the vehicle is in Tyntetown itself or out in Pontcynon. Switch nothing on, call 0333 366 0103, and count on a thorough flush after a drain, carried out just where your car sits around Tyntetown. When your motor has been run, stop somewhere safe first, then turn it off. It is a larger job, yet step one does not change. Find the situation below that matches yours, wherever in Rhondda Cynon Taf it happened. ## Tyntetown forecourt: AdBlue in a diesel at the pump Picture it: stood by the pump, gripping the nozzle, you realise the filler you opened wasn't the right one. Somewhere in Tyntetown, then — Texaco, Gulf Treharris Service Station, or somewhere else close by. Meaning? Spotting it here is the best it gets. Still inside the tank, with no fuel pulled through: that's where the AdBlue sits. What to do: don't get back in and start it to clear the petrol pump. Ring us from the forecourt once your vehicle sits in a bay — the staff will lend a hand to roll it — and save the bottle. Can't move the vehicle by the pump? Our explosion-proof kit makes a live forecourt safe, and so we can drain the vehicle where it is. ## At home in Tyntetown with AdBlue in your diesel tank On your dash, a warning had shown all week. Only by the recycling, the empty bottle in hand, did you look back at the cap you had opened at the driveway. Driveways near Main Road get it as much as any other street. Put simply: if your car hasn't been driven since, it's nearly equal to finding out at the pump. As it is unable to mix, AdBlue drops to the base in your tank and waits. One night standing changes none of that. What to do: leave the keys inside the house so nobody moves the car in the morning. Then ring. Your drive is where it gets drained, whether in Tyntetown or Bryntirion. Late-night drains outside a house are fine: the pumps are low-noise. ## AdBlue in a diesel and already driving around Tyntetown? You filled up, set off, and a mile or two later the motor began to run unevenly, smoke, lose power or light up the dashboard. Perhaps it was on Milbourne Street, possibly on the way out towards Cardiff, under 15 miles away. The point: the system has drawn AdBlue in by now. Mileage sets how far it gets: filter and lines first, then the high-pressure pump and each injector. More miles, more restarts: deeper it goes. Stop safely — that is the next step — then turn it off. Services further on are too far: from the M4, under 15 miles out of Tyntetown, use the next junction. Don't restart the car to see if it has cleared; it will not have. Call, and say how far your car went. ## AdBlue in the wrong tank of a hire, lease or company car A week back, the car was unknown to you. Your own motor either does without AdBlue or puts it somewhere different, so nothing warned you the AdBlue inlet sits just beside your diesel. Anywhere you are across Rhondda Cynon Taf, every driver can slip up. Put simply: one extra stage on top of the cases above, which depend on whether it's run. Plenty of hire and fleet contracts require the owner's approval before work. What to do: call the hire firm or your fleet manager first, then us. That is quicker settled before our technicians arrive than after. Stranded near Penrhiwceiber Clock Tower And War Memorial or at Penrhiwceiber till someone replies, your vehicle remains switched off the whole time. ## Not sure it was AdBlue in the diesel tank, Tyntetown? "I think so" is sometimes the most honest answer there is. The bottle is lighter than it should be, there's a faint smell of ammonia round your filler, and you cannot remember which cap you took off. It might have been on a friend's drive in Perthcelyn, or in a rush by the local primary school on the school run. Meaning? Drips outside the inlet don't reach the engine at all. A diesel tank with AdBlue in it is another story. Any AdBlue in your tank will be sucked in by starting the car, and the start wouldn't settle which it is in any case. What to do: treat it as if it was put in. Do not start it. Describe what you saw on the phone. A clear tank looked at is a better result than a run one drained. ## What each AdBlue drain around Tyntetown has in common The work opens identically, whichever the situation. Forecourt, driveway, Tynte Hotel Freehouse's car park or a road beside Penrhiwceiber Institute and Community Hall — the van reaches your vehicle, and three answers follow: which fluid, which quantity, and whether it has run. Those answers settle this work, and you hear the quote by phone, before anyone heads out. Then the tank is drained and your system rinsed thoroughly, which counts more with AdBlue than with petrol: AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't rinse out on its own. Finally are the filter, flushed or renewed as needed; fresh diesel; and a test of your car. If your engine has not run, the majority of jobs take about half an hour once we are there. Firing it up comes at the end. Our engineers check it runs correctly on fresh diesel before leaving. Our engineers do the entire job where the vehicle is, and lasting damage is very rare if it has been spotted quickly. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Many policies cover misfuelling, so check yours as we head over. ## About Tyntetown, briefly Tyntetown is a suburban area in Rhondda Cynon Taf, situated on the riverside at an elevation of 122 metres.
